If you want to get rid of the number pad on your iMac desktop, you now have no choice but to go wireless: Apple has quietly discontinued its compact wired keyboard, making either the $69 Apple Wireless Keyboard and the $49 Apple Keyboard With Numeric Keypad the only (official) keyboards in town.
The compact wired keyboard — part number MB869LL/A — was introduced in early 2009 with the new iMac revision. Neither it nor its wireless brother (which came in the same design, albeit without the compact wired keyboard’s two USB ports) have ever been my style: I’ve never been able to grow accustomed to the lack or miniaturization of some important keys, let alone the omission of the number pad.
Still, if you like keeping your desktop as compact as possible but don’t like changing batteries on your keyboard, it’s a bit of a blow. Better stock up: Amazon’s still selling the old wired keyboard for $49.
