I have found the Pocket PC 2002 OS to be severely inferior to Palm OS 5.2 when it comes to smartphone functionality. Pocket PC 2002 gives you nothing that PalmOS 5.2 cannot give you. Palm OS smartphones typically give you the functionality in a smaller, faster, leaner design as well. I was a G1000 owner and am now a Treo 600 owner. No comparison...G1000 was an ugly beast that was LESS functional than the Treo 600 in many ways.
