I got my first iPAQ about the time this site started, but my work recently bought us all Treo650s. I really don't like the Palm OS (only one address per contact!) and it crashes more often that Windows ME (esp. using bluetooth), but the form factor and size are absolutely incredible. I though the keyboard would be wasted space and the square screen useless, but now I'm finding the device to be very helpful and productive - and the screen resolution is stunning. They keyboard seems essential for any device that connects to the internet and the Treo keyboard is usable without placing the device on a flat surface.
The only thing that could make it better is if it ran WM 5.0
