The MiLi power pico projector is an older but still relative device.  iPhone and iPod users alike both have loads of pictures and movies ready to be projected to an audience.

This stylish device is able to charge your apple device while plugged in but it can drain your battery if you try to run it without being plugged into a wall.   This projector also comes with built in speakers which can improve upon the apple devices speakers but it is far from a home theater replacement.

For some serious cash you can pick up this device and show it off to your friends.  There are a few alternatives in the pico projectors world that can give you the same quality picture at a cheaper price.
