Microsoft is offering some pretty cool looking Universal Mobile Keyboards that work with Apple, Android, and Windows smartphones and tablets. The cover protects the keyboard when not in use, and opening the cover wakes the keyboard – and closing it sleeps the keyboard, of course. The cover detaches and has a built-in stand to support your mobile device while you work. You can pair the wireless Bluetooth HID keyboard with up to three devices and switch easily between them. The rechargeable battery should give you six months of service between charges. The Microsoft Universal Mobile Keyboard is available in gray with a white keyboard or black with a black keyboard for $79.95 from Amazon.
