A guess: Uncle is using ppc 2002. 5.2.4 worked fine on 2002. 6.x, not so much. My experience with Ipaq 3850/3950, anyway. I had better luck with ppc 2003.

PPC2003 may have some performance advantages over 2002, but 2002 should still be entirely usable. I guess people aren't reporting issues with XCSoar on old hardware because either:

a) They're used to planned obsolescence in software, and expect new versions to fail on old hardware

or

b) They think the issue is noticeable enough that the developers will catch it before the next version.

In practice neither is necessarily true. XCSoar has software mechanisms in place to scale back features for slow hardware. As long as those are maintained and extended to cover any new features, old hardware should be supported for the foreseeable future.

However, only a small proportion of the developers have access to Windows CE devices and even fewer are actively using them. If issues are reported the resources are available to fix them, but if they're not reported they'll very likely be missed.
