A lot of people's complaints with Win8 were resolved in the 8.1 update.
The only problems I've ever had were actually with third-party software companies that can't get their crap together enough to stay compatible with the latest OS. Other than that, I've had no issues.
I can understand the "if it ain't broke..." mentality, but at the same time, why would you want to be a decade behind everyone else? Besides, when your computer finally does die and you have to buy a new one, you're going to be forced to a new OS anyway. *shrug* I just don't understand people that stubbornly "hold out" on new tech.
I also don't see the point in running something that's no longer supported, and that software companies don't tailor their programs for. Also, keeping a good third-party AV program is nice and all, but what happens when that company no longer supports that version, or comes out with a new one that's not compatible with an OS 3 or 4 generations old? I just really don't see the point.
Nobody likes change....but it's part of life in the modern world, lol.
