Here is a portable foldable keyboard that makes it easier to type on you iOS, Android, and Windows devices. The Perixx PERIBOARD-805 Ergo is compact enough to fit in your pocket, weighing only 4.9 ounces. It has a magnetic switch that turns the keyboard on as you open it.
The keyboard has a V-shaped design to promote a natural typing angle. It uses a scissor-switch technology to offer a quiet typing experience. The battery lasts up to 36 hours. The Perixx PERIBOARD-805 Ergo keyboard is expected to ship later in October.[where to get it]
