I purchased a BT headset with the anticipation of using it with my 
computer to make Skype calls. I tried it, but the sound quality when doing 
bidirectional audio (whatever that mode is called) is not good enough, it 
worsens the "skype IP" call quality. I agree that the use case is 
interesting, but as long as BT sound quality is what it is, it's really 
only the "low end" type  sound quality we're talking about.

But yes, I make skype IP calls with my Nokia N900 using BT sometimes, so 
the use case example is definitely valid.
