It might be a bit short sighted, but win7 works well. It's extremely stable, reliable, does everything I need it to. I've used win 8/8.1 a couple of times so can't speak to how stable/solid it is. What I noticed was what a redundant o/s it is. How many different places and icons does a person need to access the same exact thing? Connecting to a wireless network, there's a way through the start menu, the taskbar, a tile on the right hand side of the screen etc etc. A better name would have been windows for morons. No offense but all it does is adds confusion. Ever seen a car with a speedometer on the dash, the steering wheel, an indicator on the rearview mirror, on the glovebox and for good measure projected somewhere on the windshield? Absolutely not, it's redundant and confusing. Put access to something in someplace that makes sense (aka not buried 8 levels deep in a bunch of dummy windows) and leave it alone. Or better yet allow the user to put it where they want it. Instead of being smooth and fluid it looks like they took a whiteboard where everyone puked out their ideas and opted to implement all of them. I expect something different to have a slight learning curve but it's never good when you're a long time pc user and your first reaction is 'what is THIS garbage?!'. In all honesty, linux is less confusing. I'm hoping win10 isn't just a rehash of 8/8.1 which is more or less the new vista. Win7 nailed it and these charts show that. Best to improve upon what people prefer. The whole concept of trying to combine a mobile os with a real desktop environment is a crapfest. They're nothing alike.
