Chinavasion has a pretty sweet looking 2GB MP4 player for sale that comes packed with all sorts of goodies, including NES, Gameboy, and Gameboy Color emulators. All this and it's solar powered.
Uniquely designed 2GB MP4 Player with 2 solar panels built in for either recharging the built in Li-ion batteries or for recharging other electrical devices through the USB OUT. The eco friendly MP4 player has the ability to recharge 4.5V, 5V, 6.3V, 9V devices, so you will be getting a mobile power station wherever you go. Other excellent features include a 3.5 Inch TFT Screen with a 1.6 million colors, a NES, GB and GBC emulator, an E-Book that will read aloud for you, and even a built in LED flashlight.
They cost $123 and are available from Chinavasion if you're really interested. But don't screw around -- if you're not really interested don't lead me on. Because that's how feelings get hurt. And when feelings get hurt, arms and legs get broken.
