yea.. thatz what i said lol, but alot of devices now have that, most smart phones and laptops.
The things self you would wanna sync, black berries, queerphones and awesometude e71s. Even some NAS have them both, and throwing in a usb Bluetooth dongle on your desktop would remove the need to tether to sync movies or mp3s..but would still probably tether anyway to charge the phone.
