PC Magazine checked out a small projector from Mitshubishi, here's a snip from their review:

Just one look at the Mitsubishi PocketProjector ($799 direct) is enough to set any gadget freak's heart aflutter. It's small enough, at 1.9 by 4.9 by 3.9 inches (HWD), to fit on your palm, and light enough, at one pound, so you hardly notice the weight. It's not quite in the production stage, but we decided to preview it as the first in a new category of projectors.
