Belkin adds the Ultimate Keyboard Case for Samsung Galaxy Tab 3 10.1 to its extensive tablet keyboard line. The keyboard case is made with aircraft grade aluminum alloy, keeping it at less than 8mm thin. It easily folds flat to hide the keyboard when not in use and can automatically turn on or off using Smart Sensing technology. It also makes use of Belkin’s TruType keys for good typing experience. It can supposedly last for as long as six months with about two hours of active use per day on a single full charge. The keyboard case will be up for sale in December for $129.99.
