Is it worth switching to a Dvorak keyboard?
johnm: Naw, it's way wacko different and relatively hard to switch back to a QWERTY when you need to.Check out the Kinesis Ergo Contoured keyboard instead, http://www.kinesis-ergo.com/.  While it looks daunting, it's easy to pick up and it's surprisingly easy to switch back and forth to a normal QWERTY keyboard.
