Twenty-seven years after introducing the world's first graphing calculator, Casio has developed its most sophisticated educational Game Boy ever. Indeed, the new Casio fx-CP400's 320 x 528 resolution screen isn't just colour—it's a freaking touchscreen that flips from vertical to horizontal. That's a far cry from the drab 94 x 64 display on the the Casio fx-7000G from 1985.

Man this tech has come a long way. Let's hope the kids do more than play Drug War on the fx-CP400 when it's available next summer. [Casio via Engadget]
