Well, I'll put it this way (and caveat: this is just my own perspective).
When Vista came out it was a major departure from the then-current XP mindset. That might have been okay, but Microsoft had screwed the pooch with schedule, stability, UAC, a lot of things, so Vista was correctly perceived as a great blunder -- even though it had tremendous advances under the hood.
Windows 7 was essentially Vista, but done properly. And it rocks.
Well, Microsoft repeated the pattern. Windows 8 was another major departure from the Windows 7 mindset. But they screwed the pooch again, this time by trying to force the Metro interface into an environment where it made no sense (the non-touch desktop), so Win8 was correctly perceived as a great blunder -- even though again it had great features and capabilities under the hood.
I view Windows 10 as essentially Windows 8, but done properly.
We have yet to see if it rocks, but IMO the prognosis is good.
Do you wish to be on the Windows Ping List?
If it keeps all those annoying Sesame Street “blocks”, I’ll be passing on it but sure, add me.
