Too Bad...I used Palm for about 7 years and just switched to the Mogul last August, because my 700p just couldn't cut it anymore, too many crashes and resets from certain applications, also the 650p, 700p, 680p, 755p, and Centro all are running the same lame ROM that is about 4 years old now. They are going to scrap that OS and switch to Linux in early 2009.
Here are some web sites:

From what I know there is no way to swap from Palm OS to Windows OS on a device.
