I really needed the number pad and yet hated to have to buy a wired keyboard, when my old "white" wireless keyboard was a full one. I just bought the Microsoft Bluetooth Number pad from Amazon for $36. It's high quality, all black finish, so looks and works great with the new iMac. I've tested it and it is very nice to have it sitting wirelessly next to the new Mac wireless keyboard. But SHAME on you, Apple, for not making this yourselves, and forcing me to place a product prominently labeled "Microsoft" alongside my iMac.
