I'll start the ball rolling. - Whenever my Mac is connected to my TV and I unplug the DVI connector while I have the brightness down on my Mac, I cannot put the brightness back up. The laptop ignores the command. - AirDisk's have improved a LOT, but there is still some slight problems when using two external hard drives and a printer. That's all so far. Not that I'm dissing this update, it has fixed so many of the issues I was having. But there is still room for later improvement.
