One point of discussion about Apple's new keyboard is the absence of the Apple logo on the Command-Key of the keyboard. It seems it may not have been decided upon until late in the release (or reserved for international keyboards?)

Interestingly, Apple's Spanish site (and other international sites) has a photo of the iMac keyboard with the Apple logo still on the Command key. Apple's U.S. site shows the proper image.
Update: Apple has corrected the keyboard to reflect the "Command" labeled button.
