I recently bought a Creative d80 -- Bluetooth wireless music box and my impression is WOW!! It is very cheap just less than $40 and the quality of music is impressive. I can stream over Bluetooth from my iphone, ipad, android, winphone, and windows 7. I don't have a Mac but it seems as easy as the remaining ones. If you have win7 make sure that your Bluetooth device has a stack supporting a2dp or enhanced data rate.
