21st-century science has all the necessary principles to create a working Star Wars lightsaber, but not the know-how.

Color me surprised: Kobo’s finally beaten Kindle with its latest ereaders

[ad_1]

Color ereaders aren’t new – brands like Onyx and PocketBook have been making them for a while – but I’ve been waiting a long time to see a color-screen Kindle or Kobo. It’s finally happened with the Japanese-Canadian brand today (April 10) announcing not one, but two new color ereaders at the same time!

Called the Kobo Libra Colour and Kobo Clara Colour, both tablets are upgraded versions of the existing Libra 2 and Clara 2E ereaders, now using a different screen technology called E Ink Kaleido 3 in place of the monochrome Carta 1200 in the previous models.
