A visit to
www.brighthand.com may help. The discussions there cover a lot of territory about Wireless PDA use, file transfer, synching, and so on. I have used both Pocket PCs and Palms with each having advantages and disadvantages. Pockets PCs tend to transfer files directly, Palms tend to convert in and out, but that depends on what you are doing. Some Palms look like a USB drive when cradled but they don't have a USB port per se.
