best mouse. too bad it's discontinued
4 of 4 found this helpful it is really a shame that this mouse has been discontinued. the blue track ball of the new wireless version is not nearly as durable, and the tracking sensitivity and accuracy degrades with time. despite the fact that this red ball version is so old, the tracking still works great. and no, i'm certain its not dust/residue interfering with the blue ball tracking because i clean all my track ball mice frequently.
