I have a big Microsoft mouse that must be 5+ years old. Its plugged into my macbook. Its great, big (yet light), comfortable and reliable. The mousewheel is pretty big and still works perfectly despite all the sticky stuff that it collected over the years.
I think I'm gonna use it unltil it stops working (which will probably never happen, USB will probably be outdated before that ever happens). They dont make such hardware anymore, do they?
I have seen newer genius mices loose their color after one year of usage, and also the tiny scroll ball on apple mices break down after some usage... Besides I have yet to find one that fits my hand so well.
This Microsoft mouse is simple, basic, was rather cheap back then (not the cheapest, but well worth it).
That one, exept mine is yellow-ish beige.
