I've been using the Natural Ergonomic Keyboard for probably 20 years. While there are other keyboards out there, this is the one that seems to help best with my arthritis and carpal tunnel. The keyboard is also especially useful for men (or women) that have extra large or larger hands. The only complaint I've ever had is that the white lettering on the keys fades all too quick. If Microsoft, or someone connected to their accessories division, reads this comment then please consider creating a keyboard that is backlit and that uses better print on the individual keys. Other than that small issue, the keyboard is fantastic and the reason I have for is that each time I buy a new one I move the used one to another computer. So far I have the new one on my home office, a 2nd one in my small music studio, and a 3rd one on a secondary computer in our guestroom. The 4th one has been moved to reserve duty. By it, you'll like it.
