I have one, had it for about a year now, if you're an emulation nut or retro gamer, this machine is awesome, go get one - full stop!
UAE4all needs a little tweaking to get the most out of it, I have many A500 games working at full tick, with sound, with the GP2X clocked at 250-266Mhz.

Make sure you have the virtual device input (start button) set to -joystick only- to stop those freezes during Speedball2. And you -can- have sound during play, just set the CPU<->Chipset slider all the way to CPU, sound = faked, overclock = 250+ and frameskip = 3-4 or Auto.
Try UAE4all-tweak for slightly better performance.
Enjoy.
