The animation on the games is pretty good, better than I was expecting. The "touch screen" is actually just a 4-way rocker. Pretty fun way to control games, but obscures the screen for no good reason. It takes 3x aaa batteries, no word yet on battery life as they're still holding a good charge. You can pop off the battery case with a small screwdriver or coin. After which you can pop off the front blue bezel, which exposes 4 small screws holding in the mobo. You pop this out just like an eee mobo (one pin, careful with the ports). Looks like it's running a samsung-831 firmware, K9G8G08UOB pcbo nand. No transistors between the battery compartment and the mobo, taking straight 4.5v. Plays mp3, wav, and ogg. Another potential rockbox target?
