The Palm Tungsten C has built-in WiFi and it is the only Palm I would consider. As Scott said you get way more bandwidth and free wifi is popping up in many places. More and more you will see WiFi in corporate environments as access points now have good security. There are hundreds of very good reasons for WiFi in a PDA. I like the Skype or especially XTen as that is a way-cool communications tool. Also the new Pulver communicator.
