I'm a Skype user. Now that I'll have a 650 bluetooth phone, I'm considering getting bluetooth adapter for my laptop so I can sync with it wirelessly.

So that got me thinking...

1. Is there a bluetooth headset that anyone would recommend so I could Skype wirelessly as well?

2. If so, could I listen to music through them as well?

3. If have a software firewall, does the bluetooth adapter introduce any new significant security risk?

4. with XP, is any software required for the bluetooth adapter, or are the drivers native in XP?

Thanks in advance...
