When Mitsubishi's original PocketProjector came out more than two years ago, it literally defined a new category. It was the first projector to combine a DLP chip with an LED light source, letting it fit in a minuscule form factor—nearly pocket size. (Well, it could fit in a pants pocket—just barely—but only if you didn't try to fit the power block and cables in at the same time, and didn't mind taking a chance on ripping your pocket when you jammed it in.) There are still only a small number of LED projectors today, but it's a growing category. The PK20 PocketProjector ($895 direct) is Mitsubishi's second-generation entry.
