6 visions for your future computer

Typing on cramped touchscreens is now an everyday practice, but it's still awkward. Celluon's Magic Cube aims to be a virtual keyboard you can link up to your smartphone or tablet for a full-size typing option.

The Magic Cube's first version got mixed reviews. Laptop magazine criticized the Cube's "complicated" setup and its wonky layout -- the comma was in the wrong place, for example. MacLife reviewer J.R. Bookwalter called it a "neat idea," but missed the tactile experience of a real keyboard.

Celluon sells the Magic Cube on its website right now for $170, but it says a new version -- half the current size and priced at $130 -- will be unveiled in January at the Consumer Electronics Show.

The company is also working on an embedded system to integrate its technology into mobile devices, according to spokesman Chris Chon.
