I haven’t had a keyboard with a numeric keypad in many years, but my hand still automatically starts to move to the right whenever I need to enter numbers. I considered buying Apple’s wired keyboard with a number pad, but it’s too big to fit on my desk and allow room for my mouse. Satechi has a Bluetooth accessory that’s just what I need. The Bluetooth Wireless Smart Keypad is compatible with both PC and Macs, but its styling mimics that of Apple’s Bluetooth Keyboard. (It’s just a bit longer to allow for a display.) You can use it as a numeric keypad for your computer, or you can use it in standalone calculator mode – and even send the result to your computer. It’s normally $49.99, but it’s on sale right now for $34.99.
