Smartphone displays are not great for sharing, at least with a large group of people. So the combination of phones and miniature projectors was an inevitable pairing, I just wish the results weren't so clunky.
Don't get me wrong; when you compare Brookstone's new iPhone Pocket Projector case with the projector mounted to the ceiling of a conference room, it's downright miniscule. But when it's piggybacking on a device designed to slip in your pocket, it's not so tiny anymore. The case was developed by Texas Instruments, and uses their LED DLP pico projector technology to muster up fifteen lumens of brightness and a resolution of just 640x360. It's claimed to produce an image about fifty inches in size, but as usual, that's assuming you're using it in a really dark room.
