I own a Compaq 3650 - recently aquired.
I used to own a low end Palm pilot.
If you use Outlook at work, the iPAQ integrates more closley than the Palm, as with Windows CE you are actually running a veriosn of Outlook instead of importing and translating. You also have pocket word and excel which I have found helpful.
The ipaq also has multimedia - sound recording, the ability to play movies and surf the net, but I doubt I will use them - I have a laptop. But the iPaq goes with me to every meeting. I no longer walk in to rooms clutching fistfuls of printouts - I keep it electronically.
I am getting used to the difference in handwriting recognition.
I really like mine. But personal prefernces are important.
