Hardware Recommendations - Desktop Bluetooth Module

[Jonathon Suggs]

Does anyone have a good recommendation for a  Bluetooth module/adapter 
for the desktop ?  Features: Bluetooth 2.0, good support under Ubuntu, 
and also provide most all of the Bluetooth profiles.

I don't mind a dongle, but would think that having an internal card 
would be less likely to get broken...since a dongle would always be 
protruding from the case.  Thoughts, opinions?  What does everyone else use?
