An anonymous reader writes "Popsci.com has a writeup on 3M's new pocket projector, the 3M MPro 110, set to launch on September 30. 'In a dark room, it could project a big enough image to be the ultimate cheap-o home theater. The projector will sell for a mere $359. It doesn't have a speaker, so you'll have to get that separately. But really, how good could a microscopic speaker jammed into this thing sound, anyway?'"
