If your hand is flat, which 99.9 percent of mice are designed for, then you run the risk of Carpal Tunnel.

Stick with vertical mice. You'll be used to it within two days.

these are angled for the natural posture of your hand. they are very comfortable like the mx laser line.

Carpal tunnel or look like an idiot? Decisions, decisions.

That's kinda the point of the flat mouse. Any angling of your wrist up or down, comfortable or not, and then use of your fingers can cause carpal tunnel/repetive stress disorder. Keeping your wrist flat avoids this.

Nope. "Flat" is NOT neutral. In a "typing" position, your radius and ulna cross. Many mice also result in the hand being tilted up at the wrist. A more "natural" position is with the forearm in a neutral position, which is not quite vertical. Some of the vertical mice are just as bad as the flat ones, as they force the user's hand to be too vertical.

It giles me when I hear the term 'natural' applied to keyboards and mice.

Mousing and typing are neither natural or unnatural. Our hands are designed (by the evolutionary process) to do a wide range of things, including typing and mousing. So, everything we do is 'natural'.

I'm no M.D., but it seems to me that the problem comes in when we do a particular motion over and over again. When we lift excessive weight continually our bodies respond by strengthing the affected muscles, but the first thing it does is supply extra blood to the existing muscles to help alleviate the strain, and the existing muscles and tendons swell, which can cause irritation, degeneration of the sheaths that surround the tendons, and so on.

By rotating the wrist, hand, fingers, whatever, by using the ergonomic mouse or keyboard, we excercise different sets of muscles, hopefully those that don't affect the sheaths adversely. That 'sweet spot' is different for everyone, which is why the keyboards are often adjustable, and ergo-mice don't work for everyone.

So, it isn't a 'natural' position that we find, it's a postition that causes the least damage as we continue to do what we do, which, again, is neither natural or unnatural.

OK, I'm un-giled now. Please continue.
