In addition to functioning as a wireless Bluetooth keypad, it doubles up as a calculator that can help you solve your math problems without you having to turn on your computer. You get buttons for functions like memory recall, percentages, and decimal changes; so you should have no problems handling basic calculations with this device.
And when you don’t need it for calculating figures, it works pretty well as a wireless keypad that you can map to play your favorite games on the computer. While it was designed for Mac OS X, it works on Windows as well. It is available now from the Apple Online Store with an MSRP of $59.99.
