I just bought a 12"PB and would like to be able to sync up everything from my desktop to it - without having to open a .mac account. Possible? I have bluetooth installed in both...as well as they're both part of the same network. Any time I try to "add device" on either machine- they ignore eachother...and oddly enough, my laptop ignores my phone (which I suppose is good since it says to only sync a phone with one computer). Help?
