Query: Great wireless mouse and a solution for arthritis

I have always found Logitech TrackMan mice to be really, really good: easy to keep clean, smooth action, dependable, durable, and reliable. And my wife, with serious arthritis, finds the TrackMan to be much easier on her hands. We were worried that the new, cordless models might not be as useful.But it is even better! I have become pretty jaded about hardware manufacturers lately, but Logitech has reinforced my loyalty with this product. Good price, very easy to install, and really useful!
