Everything about Logitech MK850 Performance Wireless Keyboard and Mouse Combo has been built with comfort in mind. If you do a lot of typing, you'll enjoy the oversized, cushioned palm rest and curved keyframe. The full-sized keyboard has concave keys with a large strike area to help prevent unintentional keystrokes. Also, 3-position tilt legs let you angle the keyboard from flat, to 4- or 8-degrees for optimal alignment.
