It seems that all the PDAs I know about have problems:

- no external power connection for the Palm m100 and slow

You can live without external power, I used NiMH rechargeables, and could easily
get 7 or 8 flying hours per charge. It is slow, though...

- Compaq Aero 1500 displays fade out in a sunlit cockpit
as they get hot

True, but keep a white cloth or hat over it until takeoff, and it will be fine.

- IPAQ 3630 and 3850 get hot and crash in a sunlit cockpit.

My 3950 has never crashed due to heat, even when the temperature exceeds 40C on
the ramp. The screen is also unaffected.

Are there any other WinCE PDAs I should be looking at?

The Axim is inexpensive, but finding an appropriate mount may still be a
problem.

I'm primarily interested in using a PDA system to display a moving map
for general navigation and restricted airspace avoidance.

The upcoming replacement for the low-end Palm Zire interests me. It allegedly
has a decently fast ARM processor running PalmOS 5, 8 mb of memory (instead of
2), an external power jack, and a high contrast monochrome screen like the m100.
The main problem is likely to be finding a way to get GPS data into the thing...
