As far as I'm concerned, W7 offers the best user experience still; People who have no interest in IT or computing come to me at work - out of the blue - and say "Windows 8 is awful, is there any way I can make my new laptop better?"
I start by pointing people in the direction of Classic Shell or Start 8 but I have done so many downgrades to 7 that I have lost count. Maybe two dozen reinstalls ago I started just using a sysprepped W7 image with all the common chipset drivers preloaded.
Historically Microsoft has never managed to persuade consumers that their latest product is better - consumers have made their own damn minds up - so if legal avenues of W7 acquisition dry up, people will turn to the not-so-legal alternatives.
