The Asus MyPal A730 looks amazing in print, with it's VGA screen, but has features I wouldn't pay extra for (camera). I haven't seen one yet so I'll wait to pass judgement.
If you're doing just Word, Excel (and other assorted contact, email, and notetaking) work then get the cheaper ones. The new Dell X30 series looks neat, and is fairly cheap. Maybe wait until there are other VGA models. Using my Tablet PC has me craving higher resolution on the handhelds.
(I have a Dell Axim X5 (for work), Sharp Zaurus (pesonal use, fun to use as a hotspot finder), and an old iPAQ 3670 (backup for work, this thing is a tank... and weighs as much).
