Need a really portable projector? This little device works with computers, cell phones, MP3 / Mp4 Players, PDAs and more. Unlike others, this one works with more than just Apple devices.

3M Pocket Projector MPRO120

It fits in the palm of your hand, weighs about a third of a pound, and projects an image from 8″-50″ in size. The battery life is about 2-4 hours, so it should last through a decent movie, or maybe half of Titanic.

The energy-saving LED light lasts 20,000 hours and provides up to 12 lumens of brightness without ever needing to change a lamp. Since they’re LEDs, the heat output would be a small fraction of the normal fire-starters included in older-style projectors. Although the image won’t be as bright as a larger model, the portability would more than make up for it.

To connect it to an iPhone or other Apple device, you’ll need an optional cable, so be sure to pick one up. I could see using this connected to a digital tuner box, as a replacement for a flat panel TV. Click the image to the left and see the other pictures on Amazon’s site that show how small it really is.
