I saw an ad for it; essentially it's an open-source Linux portable device that runs a full gamut of emulators, allows for people to create and play their own games, and plays DivX movies, mp3s, e-books, etc. etc. etc. It uses SD memory cards. It seems to be selling for $150-200.... at first I thought it was intriguing, but then I thought "Can't I get a used PSP for the same price and load virtually all of the GP2X's capabilities onto a memory card, plus have online capabilities?" Anybody with thoughts or experiences to share?
