I finally got around to purchasing the GP2X, a Linux-based hand-held game console and media player.
I have wanted to acquire one for a long time and I now realize that I should have bought it a long time ago.
It is a great product and has a great community behind it as well. I foresee myself mostly using the GP2X for playing my favorite console (e.g., NES, Sega Genesis, etc.) games on the go via emulators. Interestingly enough, that seems to be what most people use it for as well..
Here are some videos of the GP2X in action in case you are interested.
