This is the "bad" side of those "good old" technologies, they were build
to last forever ! I can't explain (or can explain too well :-( ) that
some computers I own are still running on their 10 years old hard
drives, when I have to change my sata's nearly every year. Your mouse
will never fail, see you 2100 for a universal pointing device hand
implant, complete with "eternal®" nano batteries charged from
body-derived magnetic and kinetic energy !

See how devious I am, now you are doing the advertising ;-) .

I am a heavy user and usually the buttons give up after a few years, or
the plastic/rubber casing starts looking really ugly. I admit I like it
fresh too, so none of my actively used pointing devices are older than 5
years (sitting in a box doesn't count, right ?), the two I or my wife
use the most are under two years.
