I have the rx3715 which is THE bomb diggity for Multimedia. It has a 1.2 Megapixel Camera, video, bluetooth, wifi, I.R., and the list goes on.... In my opinion it's tops! There is a utility which comes with the PDA that allows you to control all of the media on your computer through WiFi; the program has a server that runs on your desktop, then you connect to the PC and can play Movies, Music, and view Pictures. It's pretty dang cool. Makes me wonder why I'm building a car pc....
