Sometimes I feel like one of a half dozen people in the world who don't have problems with Windows. Yes, I went back and forth between 8.1 and the TP several times, but that was usually because of usability issues, not technical difficulties. Things are pretty peachy for me.
I've spent a lot of my life being an uber-geek and an early adopter. I'm a fanatic for backup so I don't lose critical data even if I do something that makes my machine go belly-up (a frequent occurence in my Linux days). I still love messing around with operating systems, even old ones (ooooh, what's that on my hard drive? A CP/M emulator? Cool!). But as I get older, I find myself happy with a working system that doesn't get in the way of what I want to do. Windows has pretty much always been that for me.
