8.1 will be supported until 2023, probably longer than I'll be around.
I hear ya. For me, the point of the Windows operating system is to run my critical Windows-only apps, period. I have Mac and Linux boxes for fussing with building software and playing with OSes. The years I spent building software for Windows are long over; now I'm just a user on that OS.
Personally I intend to get the free Win10 upgrade for one of my Win7 systems, but the rest will likely continue to run Win7 for another 5 years until security upgrade support runs out in 2020. I'm not a fan of the Metro interface, and while Win10 is substantially better than Win8,x in that regard, it still bugs hell out of me. I'll use my upgraded Win10 to try to get used to it, who knows... I've adapted to weirder things than that, I suppose. :-)
