Just tried BT for the first time this AM. Got my Dell/Vista to see the Droid, but the Droid says "Paired but not connected". When I try to connect by long-holding the Dell entry in BT settings on the Droid, I only get the option to "Unpair".
The two devices have no profiles in common. You can install the BT file transfer app, and then they should appear connected. The file transfer is only one way, I forget which because I just use USB.
Otherwise, there's nothing the computer is offering that the Droid cares about. You can also look at what services your Dell is offering if you're expecting to, for example, play music from your Droid on your Dell's speakers.
Thanks Sleeve! I'll try the app.
