Odd....I can adjust the volume and pause music on my N800 without having to look at it.
Can that be done on the iPhone/Touch?
I can even stop, start, pause, jump tracks, and answer phone calls on my N95 while it sits in my pocket all using my MotorolaS9 A2DP headset too.
Of course, neither the iPhone or the new Touch iPod can currently do that. Probably in a month or two there will be yet another new-and-improved-stereo-bluetooth-ipod-dongle for folks to dish out an additional $50+ for in order to even get the current functionality of either my N95 or N800. Granted, A2DP on the N800 requires some "hacking" but once setup it's easy to use and works well. I expect Nokia to HOPEFULLY get A2DP rolled into the next N800 firmware [this is your first and last hint on this from me, Nokia, get a damn clue already].
