We have seen plenty of awesome keyboards in the past. The E-inkey E-ink Keyboard Concept kicks butt though. This awesome concept describes a keyboard with E-ink keys. That’s right boys and girls. You can customize the buttons for different programs without having to do anything to your keyboard physically (like putting labels over the keys). E-ink is an energy saving technology, so the keyboard should last a while per charge. Overall, this is a pretty exciting keyboard designed by Maxim Mezentsev & Aleksander Suhih.
