I have an ancient Ipaq 3850 (CPU StrongARM 200Mhz, pre-Xscale) , upgraded to WM2003 and it used to run an early build of PocketUAE fine for the better part of the last two years. Speed wasn't too bad either, provided sound was turned off.
Then my battery died and I had to reinstall everything; I haven't been able to get it to work since. I suspect that some change in the later versions may be to blame. One of these days I'll have to search for an older version and see if that works.
If you're desparate for amiga-like gaming, try CastCE (atari ST emulator). Works like a charm, but then again it's not amiga...
