Using a tablet for business is a smart idea. Adding the Universal Foldable Keyboard from Microsoft is a smarter idea. The keyboard is the perfect travel companion being only 11.5 mm thick when folded in half. This lightweight compact design can be paired simultaneously with two mobile devices and can instantly switch between them with a single touch. Draft emails and text messages with greater speed and don’t worry about the occasional spill. Just wipe it off and continue. The keyboard is compatible with Android 4.3 and up, iOS 7 and up, and Windows 8.
