Keyboard with OLED displays instead of keys

Neat idea, but I dunno if it has much future. I figure touchscreen tablets are the way of things to come; there still wil be keyboards for a good while, but I think the days of marketable major keyboard advances are numbered. Sure, touchscreen is pricey yet, but just look at what's happened to its pricing - and availabily - in the past couple years. In fact, touchscreen technology right now can do everything that keyboard does, and more, all with no moving parts.
