The best utilities are often those that do just one thing but do it very well. That’s the premise behind Numberkey for the iPhone that turns your phone into a wireless 10-key numberpad for your Mac. That’s it, that’s all it does but let me tell you it does it very, very well indeed. You download and install the Mac utility on the system you wish to augment with Numberkey and do the same for the iPhone version which will set you back a cool $1.99. You fire up Numberkey on the iPhone and then on the Mac and bingo, you now have a skinnable 10-key for your Mac. I have been playing with this for a while and it is simply brilliant in its function and the utility it provides. Well done all around and highly recommended if you need a 10-key.
