This may seem like a silly question to some of you, but it has been lingering in my mind since the introduction of the Mac Pro... How does the eject key work on the keyboard if you have dual SuperDrives installed? Do both trays open? That seems silly, if that is true...or is there an additional eject key on the keyboard? I'm assuming it will work the same way the old PowerMac G4's did, but I do not know how that worked either. Not a big deal, just curious! Thanks in advance.
