I have a friend with an Asus Transformer hybrid and he likes Windows 8, but it's also exactly the kind of device it's designed for. The hate comes from trying to force everyone down that road, I mean if you big non-touch monitors then you don't want the tablet interface. I don't want to use it at work. I don't want to use it on my gaming/workstation rig. I might want to use it on an alternative to having an iPad or Android tablet. Sadly Microsoft knows they can totally ignore that market and it's not going anywhere. No, really it's not. Most of the "heavy" users are so stuck with Windows-only thick clients it'll take ages to migrate to something else. See Vista, it sucked donkey balls. Did users leave the Windows platform? Largely no. I left Windows in favor of Linux for 3.5 years and came back to Windows 7.
I hate to say it to geeks but if you look at Microsoft's stock performance they're still making money hand over fist despite what geeks think about Win8. They're not hurting. They're not failing. We hate them but Apple has largely abandoned the professional market (one trashcan design swallow does not a summer make) and Linux well I probably don't need to tell you about the current holy wars between Unity and Gnome 3.0 and KDE and whatnot chasing the tablet, nobody is taking charge to kill Microsoft on the desktop. I don't understand why everybody is leaping after the next big thing, it also means the competition will be intense. Why not try to outflank your competition or hit them in the rear in the markets they mostly ignore? When giants clash it's best not to be an ant with delusions of grandeur, you're likely to get stomped.
