The Apple Magic Wireless Keyboard pairs easily with your Mac, so you don't have to fuss with any cables. It can last up to a month between charges, but when the battery does run low you won't need to stop typing - you can charge with a USB cable, so just plug it into your Mac and carry on.
Each key is kept stable as you type thanks to the scissor mechanism built into the Apple Magic Keyboard. You'll be able to comfortably use it for longer, and its slim design make it ideal for anyone who works on the train as well as at their desk. The Apple Magic Wireless Keyboard has a number pad too, so you don't lose any of the functionality you expect from an Apple accessory.
