Apple May 2024 iPad Event: iPad Pro, iPad Air, M4, Apple Pencil, Magic Keyboard

[ad_1]

Apple’s iPads have been on the back burner since 2022—there have been plenty of iPhones and Macs since, even a mixed reality headset, but it’s been two years since we’ve seen a new tablet. Now the wait is finally over. During its virtual event today, Apple announced the next-generation iPad Pro and iPad Air, an all-new M4 chip, as well as updated accessories.

Here’s everything Apple announced.

All-New M4 Chip

Since 2020, Apple has exclusively launched its M-series processors alongside another Mac. That’s no longer the case as Apple unveiled the all-new M4 chipset debuting inside the new iPad Pro.

The new chip is built on a second-generation three-nanometer process, packing more transistors into a smaller space, enhancing both power efficiency and speed. The CPU has four performance cores and six efficiency cores, which Apple says delivers up to 50 percent faster CPU performance than M2 in the previous iPad Pro. There’s also a 10-core GPU for four times faster performance. As with the M3, it comes with features such as ray tracing, mesh shading, and dynamic caching.

The shift in strategy makes sense, seeing as how Apple’s annual Worldwide Developers Conference (which focuses on new software capabilities coming to its entire product line) is next month. In April, Bloomberg reported that iOS 18 will include “a new slate of generative AI features” and that Apple was currently in talks with OpenAI to incorporate some of the company’s features into the next version of the iPhone operating system (this is in addition to reports that Apple is also talking to Google about licensing the Gemini assistant).

During its earnings calls, Apple CEO Tim Cook has been hinting at the company’s incoming AI features as well—both in February and, more recently, earlier this month. Although Apple didn’t get into AI-specific features, it’s seemingly laying the AI groundwork with the new M4.

It’s currently only available with the new iPad Pro, but we can expect Apple to implement the chip in the next-generation Macs.

The last two versions of the iPad Pro haven’t been all that innovative. In 2021, Apple added an M1 chip and a mini-LED display; in 2022, it came with an M2 chip, ProRes video capture, and support for Wi-Fi 6E. The latest iPad Pro, however, packs the largest number of notable upgrades we’ve seen in a while.

I Rode Saga’s HoloBike and Things Got a Little Weird

[ad_1]

Matson told me that he finds wearing a headset to be too cumbersome when you’re working out. In particular, parents told him that they can’t check out with VR because they need to know what’s going on around them. However, I prefer to not have any distractions, mainly because I’m horrible at exercise and will take any excuse not to do it.

High-endurance athletes may find Saga’s offerings a bit slim, too. Matson says the company plans to ship the bikes with three to four trails in the system, each about 20 kilometers long. This is not very many rides, and those rides are not very long. By way of contrast, NordicTrack has an extensive library of rides of all lengths, levels, and programs, which also increase resistance and move up and down as you ride. Other bikes integrate with Zwift, the immensely popular online cycling platform, or collect intensely granular data that allows you to improve your fitness.

As of yet, HoloBike doesn’t do any of those things. The augmented technology, however, certainly makes what you’re seeing seem more real. And in some circumstances, not being real is a bonus. If all the trails are virtually generated, I’d love to have the ability to safely traverse places I wouldn’t otherwise go, like the streets of Mumbai, or even something entirely fictional, like a delivery route from Paperboy, or Elliott’s big take-off from E.T.

It would be cool if there were a possibility for users to design or contribute trails, too. I joked to Matson that they should make some version of a trail that goes all the way around the world, so you could circumnavigate the globe over the course of a year’s worth of rides, only to have him suggest creating a little onscreen pedal boat for when you’re crossing the Atlantic. With the HoloBike, the world really is entirely open and limitless. That’s enormously exciting.

That being said, the bike’s starting price tag on Kickstarter is $2,599, with expected delivery in the winter of 2024-2025. That’s comparable to other video-enabled stationary exercise bikes, but a lot to shell out for potential. If I’m going to ride a bike, I need something that approximates the feeling of the open road a little more closely, and for a little bit longer.

Vodafone Pro II Ultra Hub Review: Wi-Fi 6E With 4G Backup

[ad_1]

While it works well, the 4G backup is likely a superfluous extra for most folks. If your internet service is stable, as it should be if you have full fibre, you’ll never need the 4G service. Folks lucky enough to live in an area with 5G coverage can get much faster backup service or even consider 5G home internet instead of wired broadband.

The Vodafone app is pretty barebones, but it’s easy to use. You can review connected devices, set up a guest network, and easily share login details with a QR code. There’s also a built-in assistance option that attempts to automatically troubleshoot and fix network issues. Parental controls and security features would be a welcome addition.

Competition and Availability

You can pay for fast internet service, but a decent router is required to get the most from it. Sadly, most ISPs in the UK do not supply good equipment. The worst offender is BT (British Telecom), which sends most customers the aging Smart Hub 2, a dual-band Wi-Fi 5 router that’s woefully out-of-date.

Most providers at least offer Wi-Fi 6 routers nowadays. I like TalkTalk’s approach. Instead of rebadging a white-label router, it partnered with Amazon’s Eero. The slower and cheaper Full Fibre contracts come with an Eero 6, but the Full Fibre 900 includes a pair of Eero Pro 6 routers, which is an excellent system for most homes. Interestingly, Three has also partnered with Eero for its 4G and 5G home broadband service.

Pricing and availability of Vodafone Pro II service depends on your location and required speed, but it starts from £39 a month with a minimum two-year contract. That two-year commitment is a definite turn-off, and you can expect annual price hikes in April, but it is a sadly common catch with UK ISPs.

Ultimately, Vodafone has kicked things up a notch with its Pro II service, and the Ultra Hub is perhaps the best ISP-supplied router you can get in the UK today. Many folks will still do better by picking the best service in their area (depending on budget and speed requirements) and then buying from our best routers or best mesh guides, but you will have to spend a few hundred to get something comparable.

Xiaomi Watch S3 Review: Quirky Customization

[ad_1]

The Xiaomi Watch S3 is an affordable smartwatch with a highly customizable look that includes swappable bezels. It can track your health, fitness, and sleep, bring phone notifications to your wrist, and last several days between charges. The downside? It runs Xiaomi’s software, which feels a bit basic, and you can forget about third-party apps.

Closing in on a month with the Xiaomi Watch S3, I’m impressed by its tracking capabilities, considering the relatively low price, and the changeable bezels are a neat idea. But I’m also fine with saying goodbye to it. The Watch S3 has too many limitations for me, but it’s important to remember that this device is less than half the price of the most affordable option in our best smartwatches guide.

Before we dig in, it’s worth noting that there is a global version of the Xiaomi Watch S3, but it’s not sold in the US, there’s no official US support, and certain features (like NFC for payments) vary by region.

For folks who like to match their watch with their outfit, the Xiaomi Watch S3 has a unique trick up its sleeve in the shape of interchangeable bezels. Changing the strap on a watch can be impactful, but being able to change both the strap and bezel almost makes it look like a completely different device.

The Watch S3 has quite a chunky 47-mm aluminum case with angled lugs and two buttons on the right. A stainless steel bezel sits on top of the screen, and you can rotate it to remove and replace it with a different bezel. It’s easy once you get the hang, and there’s a wee marker on the inside to help you align. The bezels slot into place securely, and I never worried about them coming loose.

Attach a new bezel and the Watch S3 suggests a matching watch face. It’s a neat trick. There are more than 100 watch faces in every conceivable style, and you can even create your own. Changing the strap is also straightforward, so you can quickly change your look. My favorite of the straps and bezels Xiaomi sent was the classy green and black combo. You get one black or silver bezel with a matching fluororubber strap with the Watch S3, and alternatives must be purchased separately.

The 1.43-inch AMOLED screen has a layer of protective Corning glass. The display is roomy and crisp, but the relatively low peak brightness of 600 nits (a luminance measurement) meant it was sometimes hard to read in direct sunlight. The Watch S3 is also 5ATM rated for water resistance, meaning you can swim with it.

Streamlined for Stamina

The Xiaomi Watch S3 focuses on the basics with call and notification alerts from your phone; health, fitness, and sleep tracking; and a handful of utilities like a voice recorder, camera shutter control, and compass. It runs HyperOS, so there are no third-party apps like you will find on a Google Wear OS smartwatch.

Navigating around the Watch S3 is slick and lag-free. HyperOS is not the most attractive software and lacks a cohesive design, with a mix of dull and garish icons. But it mostly worked well, aside from the odd missed notification from my phone. It connects via Bluetooth 5.2, and you can use it with any phone running Android 8 or iOS 12 or later. I tested with the Xiaomi 14 Ultra.

Sony CRE-E10 Review: Well-Rounded Hearing Aids

[ad_1]

When Sony entered the over-the-counter hearing aid market two years ago, it did so with a pair of products: the CRE-C10 and the more expensive CRE-E10. I was dazzled by the minuscule C10—it’s still one of the hearing aid options I recommend the most—and assumed the E10 would be even more impressive. Now that I’ve finally landed a pair of E10 aids to test, I can assure you that the E10 isn’t so much an upgrade to the C10 as it is a wholly different class of product with its own pros and cons.

While both the C10 and E10 rely on an in-ear earbud-like design conceit, their general approach is considerably different. While the 1-gram C10 fits nearly entirely inside the ear, invisible enough to require a small retrieval wire to remove it, the 2.94-gram E10 is much more bulbous and visible. It looks more like a standard Bluetooth earbud than any other hearing aid I’ve tested, filling the concha with its rounded body. Since, as the old saying goes, all concha are not created equal, your comfort level while wearing these hearing aids may vary considerably. In my ears, the fit was snug but not tight—comfortable for wearing for a few hours but not all day. Sony provides just four pairs of eartips you can experiment with to help improve the fit.

The other big difference between the C10 and E10 is that while the C10 uses replaceable hearing aid batteries, the E10 features a more common rechargeable battery. The extra size of the device lets the E10 work for up to 26 hours (without streaming). The USB-C connectible and Qi-compatible charger provides enough juice for an additional two to three recharges.

Despite their larger size, the CRE-E10 aids do not feature any external controls, which is understandable because controls would be hard to access based on the way the aids sit in the ear. Instead, all controls are situated in Sony’s Hearing Control app (Android, iOS). This is the same app used for the CRE-C10, so I already had it installed, but I ran into immediate problems because the old aids were still registered to the app.

To set up new aids, you have to remove the old ones from the app. To do that, Hearing Control requires you to enter a code sent to your registered email address. Naturally, I never received the code, so I couldn’t install the new set of aids. Eventually, Sony tech support instructed me to delete the app altogether and set it up again with a different email address—perhaps not the most elegant solution, but it worked to get me up and running.

As Elon Musk Abandons the $25K Tesla, This EV Costs Just $4,400

[ad_1]

As Elon Musk steps away, yet again, from the idea of a $25,000 Tesla, let’s take this opportunity to zoom out and appreciate what a truly affordable EV can be. For this we need to ignore the Nissan Leaf—currently the cheapest EV in the US at $29,280—and skip over Europe, home to the adorable but flawed $10,000 Citroen Ami, and head to China.

Here you’ll find the equally cheap BYD Seagull, a small electric hatchback styled by ex-Lamborghini designer Wolfgang Egger and with a 200-mile range—four times that of the Ami.

But what if even that is too expensive? Then allow us to present the Zhidou Rainbow. This is a compact city EV priced from 31,900 yuan before subsidies—that’s just $4,400. For a new electric car. WIRED literally recommends ebikes that cost more that this.

The Rainbow has three doors and four seats, and an interior with a 5-inch digital driver display and a 9-inch touchscreen for the infotainment system. There’s even a connected smartphone app, charge scheduling, and the promise of over-the-air (OTA) software updates.

Splash out on the flagship Color Cloud Edition (which costs $5,800, or about half the price of Porsche’s fanciest bicycle) and you can have each panel of your Rainbow painted a different color. A bit like Volkswagen did with the somewhat mad Polo Harlequin in the mid ’90s.

Cheaper Than an Ebike

There are two models on offer. The first has that headline $4,400 price tag and is powered by a 20-kW (27-horsepower) motor with 85 Nm (63 ft-lbs) of torque and fed by a tiny 9.98-kWh battery. Spend 39,900 yuan ($5,500) and your Rainbow is fitted with a 30-kW (40-horsepower) motor with 125 Nm of torque and a 17-kWh battery pack. Range is between 78 and 127 miles using China’s generous CLTC testing standard.

Be under no illusion here, these are tiny numbers. Even the larger battery is the same capacity of that of a plug-in hybrid Honda CR-V, which also employs a 2.0-liter engine to help it get around. But the range isn’t terrible. Even if the testing standard is generous, and the larger battery has a more realistic range of 100 miles, that’s about the same as the Honda e, which cost a whopping £37,000 ($46,000) before it went off sale at the end of 2023.

There are two Rainbow models: One powered by a 20-kW (27-horsepower) motor fed by a tiny 9.98-kWh battery; and a pimped 30-kW (40-horsepower) motor version with 17-kWh battery.

An Old Abstract Field of Math Is Unlocking the Deep Complexity of Spacecraft Orbits

[ad_1]

The original version of this story appeared in Quanta Magazine.

In October, a Falcon Heavy rocket is scheduled to launch from Cape Canaveral in Florida, carrying NASA’s Europa Clipper mission. The $5 billion mission is designed to find out if Europa, Jupiter’s fourth-largest moon, can support life. But because Europa is constantly bombarded by intense radiation created by Jupiter’s magnetic field, the Clipper spacecraft can’t orbit the moon itself. Instead, it will slide into an eccentric orbit around Jupiter and gather data by repeatedly swinging by Europa—53 times in total—before retreating from the worst of the radiation. Every time the spacecraft rounds Jupiter, its path will be slightly different, ensuring that it can take pictures and gather data from Europa’s poles to its equator.

To plan convoluted tours like this one, trajectory planners use computer models that meticulously calculate the trajectory one step at a time. The planning takes hundreds of mission requirements into account, and it’s bolstered by decades of mathematical research into orbits and how to join them into complicated tours. Mathematicians are now developing tools which they hope can be used to create a more systematic understanding of how orbits relate to one another.

“What we have is the previous computations that we’ve done, that guide us as we do the current computations. But it’s not a complete picture of all the options that we have,” said Daniel Scheeres, an aerospace engineer at the University of Colorado, Boulder.

“I think that was my biggest frustration when I was a student,” said Dayung Koh, an engineer at NASA’s Jet Propulsion Laboratory. “I know these orbits are there, but I don’t know why.” Given the expense and complexity of missions to the moons of Jupiter and Saturn, not knowing why orbits are where they are is a problem. What if there is a completely different orbit that could get the job done with fewer resources? As Koh said: “Did I find them all? Are there more? I can’t tell that.”

After getting her doctorate from the University of Southern California in 2016, Koh grew interested in how orbits can be cataloged into families. Jovian orbits that are far from Europa form such a family; so do orbits close to Europa. But other families are less obvious. For instance, for any two bodies, like Jupiter and Europa, there is an intermediate point where the two bodies’ gravitational effects balance to create stable points. Spacecraft can orbit this point, even though there is nothing at the center of the orbit. These orbits form a family called Lyapunov orbits. Add a little energy to such an orbit by firing a spacecraft engine, and at first you’ll stay in the same family. But add enough, and you’ll cross over into another family—say, one that includes Jupiter inside its orbits. Some orbit families might require less fuel than others, remain in sunlight at all times, or have other useful features.

Best TV Mounting Options: Stands, Wall Mounts, Corner Mounts, Electric Mounts

[ad_1]

A rash of recent hot deals on HDTVs, even two-for-one TV deals, might have you facing a dilemma that has been with us since the era of flatscreens began: Where are you gonna mount that thing?

Of course, mounting is not for everyone. All HDTV sets come with a stand or legs to prop up the set on an entertainment cabinet or any other flat surface. If you don’t care to have your set on a wall, in a setup that can be moved around, or in some newer variation on wall mounting, a stand-up approach is perfectly fine.

But if you really want to get that set off its feet, you might be surprised with some newer options that have emerged since the last time you did this.

If you buy something using links in our stories, we may earn a commission. This helps support our journalism. Learn more.

How to Approach Wall Mounting

The wide world of wall mounts starts with the assumption that your new television conforms to the VESA (Video Electronics Standards Association) guidelines for where threaded holes are on the back of your TV or monitor. Makers of TV mounts account for these measurements when they tell you what size of television they’ll accommodate (say, a mount that works for HDTVs between 37 and 70 inches).

A standard wall mount is a metal bracket that attaches securely to a wall’s studs, paired with hooked rails that are bolted onto the TV itself. Once everything is installed, the TV with the rails attached slides onto the bracket, and you’ve got a mounted TV. Variations of this include brackets that can extend outward, swivel left and right, and tilt up and down, allowing for more viewing angles and flexibility. If you’ve only ever used basic TV mounts, you might be delighted by how useful it is to be able to move your giant TV around to avoid glare during certain times of the day, or to pull it out toward you for a closer view in a large room.

Some wall mounts can also be adjusted by remote control. Motorized mounts like Vivo’s electric mount can extend your TV outward from the wall with the push of a button. MantelMount’s MM815 can go up and down via remote, offering 26 inches of height adjustment. Bear in mind: These motorized mounts require a power outlet to function.

If you’re trying to place a TV in a space that’s not a flat surface, there are corner TV mounts available as well. For HDTVs mounted above a fireplace, so-called “pull-down” mounts that can be lowered when the fireplace isn’t in use are another option.

Orka Two Review: Sleek Hearing Aids

[ad_1]

Founded in 2018, Orka Labs feels like a bigger and more established hearing aid company than it is, with polished hardware that’s now on its second edition.

The Orka Two is something of a hybrid between prescription and over-the-counter hearing aids. The devices are registered as prescription-class aids but are sold online as OTC products. Professional medical consultations and adjustments are available (and included in the price) but are not required if you decide to go it alone.

The hardware is traditional in form, a behind-the-ear model with receivers that snake into the ear canal via flexible wires. But while they are a bit oversized in comparison to similar designs (and rather heavy at 3.8 grams each), they are distinguished by their glossy AirPod-white color and curvy, teardrop design. The units carry no physical controls, which further improves their sleekness. For behind-the-ear hearing aids, these look about as good as you could expect—and much better than the usual industrial-gray aids that are now so commonplace.

As with most over-ear aids, I found the units a little clumsy to fit and in need of significant fidgeting to situate them properly in my ears. The usual collection of open and closed tips is included in the box. While I normally find that medium-sized tips fit perfectly for me, I found all but the smallest uncomfortably large.

In keeping with its hybrid design, Orka offers two ways to configure the units. There’s a capable hearing test built into the app, which can be used to quickly make the appropriate settings. Alternatively, if you have a professional audiogram, you can snap a photo and upload it through the app. Then Orka’s in-house audiologists will tune your aids accordingly (in one business day). Any adjustments can be made by emailing or calling Orka for tweaks, though the company notes its “remote consultation” feature, where you can schedule an appointment directly through the app, is currently being revamped and is offline.

Orka’s app is straightforward to the point of being idiot-proof, with two primary operating modes. “Normal” is the low-environmental-noise mode that relies on the settings made via your audiogram or in situ hearing test, while “In Noise” is, well, self-explanatory. Here, Orka gets more aggressive with settings, using an AI algorithm to adjust its settings dynamically in response to your environment. A beam-shaping option in the In Noise mode lets you target your hearing on a single person or on “everyone.” Volume can be adjusted universally or individually for each ear.

As noted earlier, there are no physical controls on the units. Unusually, hardware controls are found on the charging case (which is good for about three charges). Here you’ll find a program button that cycles through the two operational modes and another pair of buttons for adjusting volume. Pay close attention: Volume up is paradoxically the button on the left and volume down is on the right. Despite the reversal, I ultimately found the case-mounted buttons a lot more convenient than fumbling behind my ears to find the right buttons. For users with mobility impairments, this could be a game changer.

Ambient Weather WS-5000 Review: A Fantastic Weather Station

[ad_1]

I now have a moisture sensor in my garden bed that tells me how dry my soil is, which is an awesome way to know I need to turn on my remote sprinklers while on vacation. An air quality monitor inside my workspace tells me temperature and humidity (important to monitor for some of my acoustic guitars), and another monitor really made me open the window when cooking indoors. All of these things are trivially combined by the system and displayed alongside my other metrics on the Ambient Weather dashboard. It’s the easiest thing to set up ever.

Ambient Weather recently added a better digital display that you can buy aftermarket. As I said, the one that comes with the unit is a bit retro-chic, requiring you to use physical buttons to input logins and passwords, and with only a few selectable layouts. The new Weather Window, as the brand calls it, is much larger and more modern-feeling, and it does include touchscreen controls and variable layouts, but it’s still not as fantastic as it could be.

I wish there was a way to show the weekly weather forecast on the main screen, instead of having to tap the display to see that, among other UI niggles. I do like that the Weather Window comes with a frame-like edge, which makes placing it where you might place a family photo, or hanging it on the wall, particularly easy.

By the Numbers

Most of us don’t need such minutiae in our lives, and that’s fine. For the person who wakes up and plans their whole day based on the temperature and precipitation, or who constantly checks weather radar and talks about it, the Ambient Weather system is the closest we will come to reaching nirvana on Earth.

That might not be you, but it is almost certainly someone you know. I love being away from home and knowing how wet the soil in my garden is, that my house temp and humidity are correct. I like seeing when the sun and moon are going to rise and set at a glance, and knowing how many inches of rain, at a spot above my head, we have gotten in rainy north Portland. Every time my dad and I get together, if we’re not talking about Formula One or the local soccer team’s current woes, we’re talking about what our stations are telling us.

If learning the micro-trends of your yard and chatting, meaningfully, about the weather to friends, relatives, and strangers is your kind of thing, then an Ambient Weather system, really any of them, is probably a fun thing for you to check out. You might even find it useful.
