Beam's creators envision a number of uses, including projecting games onto a table and videos onto a wall. (Presumably you could use it to project stuff onto your ceiling, too.) That said, Beam's not about to replace your TVs or monitors. For one thing, its resolution is a paltry 854 x 480 pixels--a far cry from high-definition. For another, at 100 lumens, it isn't particularly bright. (Many pocket projectors feature somewhere between 200 and 500 lumens; larger models easily surpass 1000.) It does, however, contain an LED light, so you can always have it double as a lamp. It gets all its juice from the light socket.
