Re: I will avoid Windows 10 for as long as I can
Yes, but the 8.1 / Server 2012 R2 OS doesn't require constant contact with microsoft, a raft of telemetry problems that can't be turned off, and oh yeah, random updates that break stuff, random apps that just decide to roll over and die* with MS's tier 3 team's response being "oh, you'll need to do a full bare metal rebuild and hope it doesn't happen again", oh yeah, and forced updates/upgrades regardless if you like it or not.
I'll take the funky UI of 2012R2 / windows 8.1 over that any day, every day. the OS core is solid, reliable, and understood well enough that I can get around the stupid UI issues incurred by trying to overlay a mobile interface on a desktop machine.
What apps I do use are all 'classic/legacy' apps- none of that Metro crap.
* Seriously- the CALCULATOR app is a 'Modern' app, and in multiple cases at [RedactedCo], would randomly break for our users, with nothing short of a full bare metal re-image correcting it, which was Tier 3's response after a lot of troubleshooting with MS support... You know it's bad when the god level support tier can't figure out why one of their own apps (which should be a stupidly simple thing) decides to crap it's pants at random.
