I almost bought a GP2X last Christmas. Didn't though. Now I got a Sharp Zaurus SL-C1000 shipping. I will probably be much happier with it. Right now there are still some quirks with the GP2X, it doesn't have any power management meaning that botch 200mhz processors are going at full speed all the time. This will be fixed in an update from GPH.

Seems like there are 4 Linux handheld communities now, GP2X, Nokia 770, Sharp Zaurus, and Linux for non-Linux embedded devices such as Palm and PPC.
