"The idea of stuffing a tiny projector into a handheld device isn't a new one -- we've seen a couple different takes on the idea -- but it looks like it might be hitting the mainstream soon, as 3M has announced plans to demo a half-inch wide projection unit at CES that can put up a 40-inch image. The LCoS projector is about the size of a wireless headset, according to 3M, and tops out at VGA resolution -- which seems adequate, given the QVGA resolution of most handhelds. Apparently we'll be seeing devices with the projector built in later this year, and hopefully we'll get a chance to play with a couple at CES -- you'll know as soon as we do."^^<http://www.w3.org/2001/XMLSchema#string>
