Title: The best computer accessory I've ever bought
Review: I have used the same Logitech trackball for years, on *four* different computers, and it works as well now as when I first purchased it. The color is all rubbed off, but the sensors work fine and I have never had any malfunction. It doesn't even need to be cleaned that often.My wife got a new computer in the spring of 2008 and got a fancy new black and blue-light trackball that looked very slick. It died today.Logitech - about 7 years, no problemsFancy black and blue-light - less than 2 years, dead.Spend your money here.
