I don't know if anyone had noticed this, but I just bumped the F12 button on my pismo, and discovered that it works as a cd eject button, much like the eject on a iBook. I'm not sure if this feature is new to 10.1 or has been around.
also, if you have multiple removable drive connected, it will eject them all! I have successfully annoyed myself by ejecting my DVD-drive, CD-RW and DVD-RAM all at the same time!
