It may not be as exciting as the new Mac Pros, Mac minis, or iMacs, but Apple also quietly added a new version of its wired USB keyboard on Tuesday, this one without the numeric keypad. Apple is so sure that this one is better, in fact, that it’s now the default keyboard that ships with the latest iMac models.
The new keyboard combines the ultra-compact design of the existing Bluetooth Apple Wireless Keyboard with the two USB 2.0 ports of Apple's standard keyboard.
Although standard with the new iMac, you can opt to replace the new keyboard with the Apple Keyboard With Numeric Keypad for no cost when configuring your purchase (similarly, Mac Pro users can choose the smaller wired keyboard instead). For both the Mac Pro and the iMac, the wireless keyboard is a $30 option.
If you already have a standard Apple keyboard and wish you could get rid of the numeric keypad, Apple will gladly sell you one of the new keyboards for $49.
Alternatively, you could take a hack saw to the one you already have, but I wouldn’t recommend that.
