Work anywhere with a wall, with a keyboard that's also a projector
The KiBoJet's pico projector offers 150 lumens of brightness, which should be visible under most indoor lighting. It has a full-HD resolution, and is capable of projecting an image of 21 inches wide up to 33 inches, though this spec is not yet finalized. I found the quality of the projection to be passable, but bear in mind this was a working prototype that Sho U rushed to get ready for the show, so the final product may be a lot better.
