I would love to have track skipping too, as I use it all the time. I'm curious what Apple has up its sleeve in terms of peripherals to utilize the A2DP functionality. Maybe they'll release something similar, but with volume buttons like the new iPod touch headsets? Here's hoping...
The IS800's are tempting, even with the limited functionality, but volume control of some kind is a must. Nobody makes anything close - have you seen the jaybirds?
