I'm not a Windows fanboi... Far from it. Yet, Windows 8 might not deserve the bad rap it gets in the tech world.
I think this because I remember how the tech community reacted to Unity on Ubuntu. Hey, I did react violently too, because Unity in 10.10 to 11.10 definitely sucked. I continued to use it and I have to admit that in 12.04 it has become good. Sure, perhaps a bit dumbed down for the average power-user, but I can live with that.
If you read here more often, you might think "why for hells sake did you continue to use it if you didn't like it". The reply to this is that I use Ubuntu (LTS) for a "drop and forget" for non tech users. I was utterly dreading giving them Unity.
My worries were unfounded. When my dad had to go to the hospital (twice) earlier this year (He has COPD as we've now been told and has been on the brink of death twice), I provided him with a low-weight dumpster-diven laptop (CoreDuo/4GB RAM, if you must know) on which I quickly installed Ubuntu so he could surf and email. Not a single question was asked... None. Sure, my dad is Windows power user, but really, no question at all.
I upgraded my Mom's computer to 12.04 LTS in May.. Not a single question either... My mom is no tech...
I will say it how it is: Mark Shuttleworth was right, and the tech community wasn't.
What has this got to do with Windows 8? Simple: the interface is radically different, just like Unity. It's radically simplified, just like Unity... We techs all hate it, just like Unity. However, has anyone ever bothered to sit down a real non-tech user in front of it? That will tell us the success of failing of it. Normal, non-tech users, will probably like the simplicity.
I predict that, if Windows 8 doesn't have other problems, it might not be the disaster we techs think it will be.
