OS X Leopard’s most important feature - A2DP
It’s craziness that OS X 10.4 (Tiger) doesn’t support stereo Bluetooth (A2DP) headsets. There is a hack to get something working but it should really be implemented by Apple at the system-level. When OS X 10.5 (Leopard) is released this month it will finally include this capability - no more hacks or mono headsets.
At this point I’d forego Leopard’s other features just to get Bluetooth stereo support. It’s a wireless world and so should be your stereo headphones.

are you sure this will be included in 10.5? has it been confirmed or are you just speculating?
I do not have definite proof aside from this blog post. Since I wrote this, Apple made the official announcement for Leopard’s release date and the message boards are busy again with questions about A2DP.
It appears the iPhone does not support A2DP which leaves a big question mark to Apple’s intentions. It’s seriously amiss for a company so big in the music industry to not equip their hardware with stereo Bluetooth support.
Also makes me wonder why Nokia and other mobile device vendors don’t implement A2DP across their product line. Bluetooth profiles are just software and easy to update.
