I work at a place stuck on 7 and I want 8. Many little things and a few bigger things are just better in 8. Task manager?! Search?! Snapping the metro apps (music/skype/etc) into the little slice along the edge of the screen on one of my monitors?
I've only used it on desktops and laptops and it's better than 7.
What I keep seeing is "serious" computer people who aren't Windows users, fans, or enthusiasts flailing - much the same way I flail with linux or OSX when doing the 3-5% of tasks that are not well-supported. Finder? F#&$#&$ finder? How do you organize your files on OSX?
So I see someone who feels that they should just "get" a new interface because they know how to use a "from-the-corner" menu system, etc. and they don't get it (because they didn't watch Scott Hanselman's Win8 bootstrapping video). So, obviously nobody should be able to get it... psh - LOSER operating system alert!!! Even number FAIL! Check out the penguin tattoo I got. Linux til I die.
Here's the thing. My kids get it. They aren't 10. Their mental plasticity and lack of ego enabled them to be mad functional right quick. They jump in and out of desktop mode without a whine or cry for help.
We've got 20+ years of a model of thought around approaching the machine. Someone disrupts the model, and the champions of disruption crowd roll up in a ball?
