The Logitech Wave keyboard aims to take comfort to heart with a patented design that strives to mimic the natural placement of your hands and fingers on the keyboard. Although the design is meant to make typing for long periods of time more comfortable, Logitech is not claiming this keyboard to be ergonomic but rather a comfort keyboard, so if you have carpal tunnel issues, you may not find this keyboard suitable. The keys form a U shape with variable height difference, depending on the natural length of your fingers. Your shorter pinky fingers that rest on the 'A' and semi-colon are slightly raised and the key height shifts gradually from there. The overall keyboard is raised (in the wave pattern) towards the middle keys - 'G', 'H', etc. Logitech's wave keyboard competes with Microsoft's Natural version, although Microsoft chose to go with a split version whereas the Logitech focuses solely on the wave pattern. This keyboard is also fully compatible with Microsoft's Windows Vista, incorporating new features like Flip 3D, Zoom, Photo Gallery and Gadgets.
