Small package, big features.  I received my mp3 pen today. It works great. It functions as a pen, a digital voice recorder, a mp3 player, and a USB flash drive. Mine is 512KB but you can get it with a gig of memory. The voice recorder is pretty good and the mp3 player works great. The pen includes volume and track selection buttons. Best part of all, no batteries. The pen is charged via the USB port. Just like an ipod, it charges while it is plugged into a computer.

This stuff is awesome. They will eventually make computer chips, cars, and space ships out of it. Have a look at what Wikipedia has to say about it “This material might also revolutionize refrigerator magnets which could be made entirely out of plastic instead of having a metallic magnet attached.” That is exactly what I thought first when I heard about this technological breakthrough.
