Query: Still going strong, best I've ever owned

I don't think they even make these things anymore, so I guess it's silly to write a review now, but I can't resist doing so anyway. This is a really great device, and hasn't worn out in over 6 years--a rarity in the hardware accessory world!I spent my own money for two of these, one for home and the other for work, despite being able to use company-supplied mice for free.I've never seen a better pointing device yes, although I guess I could find something if I they ever wear out. So far, with daily use, they haven't, not even the microswitch buttons (are you *listening*, Kensington?)Best thing Microsoft ever produced :-)
