Where I do my day job we stuck with XP until we just couldn't anymore. We are now with Windows 7, as 8 is maddening. We do not intend to go to 10 either. We have ironed out about 70% of the bugs, but some we may never fix and are just learning new ways to do some things.
Occasionally on Facebook I'll see something about Bill Gates. Usually it's the picture of him holding a sign with that bogus "Share this and I'll send you $5,000". Anyway, I NEVER miss a chance no matter what the post, even if it' about Gates' philanthropic activities....I always comment with something like, "Why don't you spend some of that obscene amount of money you have fixing your shitty software"?.
Just a little thing I do.
