New Apple Pro Mouse and Pro Keyboard? [Updated]
The University of Arizona's online educational Apple Store (store.apple.com) posted two items on their "Recommended Systems" page:
New Apple Pro Mouse
New Apple Pro Keyboard
Both items have generic icons, carry an educational price of $55.00 and are listed as "Currently Unavailable".
Apple's Pro Mouse and Keyboard had previously been discontinued, leaving only the "Apple Keyboard" and "Apple Mouse" which come bundled with the new PowerMacs.
While this may simply be a strange mistake, previous Panther screenshots haved provided "confirmation" of an upcoming Apple Wireless Keyboard and Mouse. And one reader report indicates that the Bluetooth Wireless Keyboard/Mouse support comes built into Mac OS X 10.2.7 on the shipping PowerMac G5.

Update: Apparently, individual schools have control over the "Recommended Systems" page so does not represent any new information from Apple.
