My Favourite Computer Device

I don't intend to write a lengthy review of praise, enough people have done that already. I've been using my Logitech Marble Mouse trackball everyday at the office since it was given to me around Y2K, and it's worked flawlessly ever since. It is very accurate, very easy to clean (I use an X-acto blade to pick out dirt), and leaves you without any wrist pain. In fact, when my wife was having wrist pain at her job due to mousing, I convinced her to have her IT department provide her with a Marble Mouse and it worked. The fact that lefties can use it equally as well was an advantage too. I have absolutely no complaints about my Marble Mouse and I intend to get more for home. I do not like the other Logitech trackballs because they tend to be clunky with too many buttons. The simplicity of the Marble Mouse is it's strength.
