Maybe my problem is Sony Ericsson...

Of course, I've found that SE has the best bluetooth implementations. So YMMV. Really though, with windows, the bluetooth drivers are extreemely important. I had a belkin PC(MCIA) card with horrible drivers that hardly supported anything. When I got a Dell laptop with whatever software dell provides, it worked much better. Then I got a powerbook where bluetooth is amazingly smooth the the point where my bluetooth headset paired easily and then showed up as a sound output device in the control panel. The night I got my powerbook I was listening to streaming radio through my SE HBH-660 (great headset, btw). The sound quality was lacking, and I've never done it since, but that it was possible and easy was amazing.
