Eagl,
My palm-powered device can view/edit word and excel, and can view Powerpoint, and it is two years old. I think new models can now edit powerpoint too, but can't imagine why you'd want to.
I mention this because I can't think of any of my clients who have been happy with WinCE *after* using PalmOS for any length of time. Once you get used to Palm's lean and mean way of dealing with a small screen, MS's cumbersome, plodding interface always seems to get in the way. Heck, I have two clients who sold their WinCE devices on ebay and went back to Palm again.
New users, in my experience, take to it rather well.
Anyway, I'm interested in what current WinCE people recommend too...
