I have a Zaurus and I can promise you, it rocks!
Lucky me, my work bought me one.
There are some difficulties getting it to sync with
Linux (I can't use AmigaOS at work so better the
devil you know..), that's why PC magazines don't
rate it. But once you have sorted it out, it is actually
a lot better than syncing with Windows. I can get full
net connectivity by running a few scripts:
on Windows the device manager thingy gets locked up
if you don't cleanly unmount it and if you want full
net connectivity it's major hassle.
The main problem for it is the QT based syncing software,
which isn't up to much. When 3rd party sync software
becomes available then most of the problems will be solved.
As for AmigaDE, if they have a Linux port I don't see any reason why AI couldn't cross compile it to the Zaurus with a few twiddles. If DE isn't on the Zaurus, I would blame AI
not Sharp.

BTW: Amiga.org looks quite good in Opera at 320x240 !
