Bend your arms at the elbows and hold your hands straight out. See how your hands naturally position themselves at a slight inward angle toward each other? Notice how this angle matches the angle of the split-keypad on the ErgoBoard Natural Design Keyboard. It lets you work more comfortably by helping you type with your hands, wrists, and forearms in a more relaxed posture. The ErgoBoard Natural Design Keyboard incorporates more than just an ergonomic design, it also includes a tactile key switch, an integrated palm rest and adjustable typing heights. This keyboard still has the familiar layout that you are used to. Using a QuietType membrane with soft tactile keys will ensure ease of use and a comfortable feel. With a 15 million keystroke operating life and a jumbo sized Enter key, you can expect reliable and convenient performance for years to come. PS/2 Compatible
