i have the newer (blue) one and it has certainly helped. i have it positioned between my body and the keyboard, on the left, angled so that my arm is in a very comfortable, relaxed position when using it. it sounds odd, but works well.
it might be worth adding that even after many months of use i still don't feel as accurate with it as with a mouse (and a friend with one feels the same). but it is certainly "accurate enough" (i have a logitech mouse, configured to use the same usb receiver, but haven't felt the need to use it). if you do need very fine accuracy i think the best solution would probably be to combine one with a wacom tablet.
before that, i found that switching hands with the mouse helped. it doesn't take long to become proficient at left-hand mousing.
