I don't know about all that article has to say. I know that I can have multiple Windows on the desktop, just like Windows 7. I can also switch to the pretty Windows 8 interface. I can also split the screen between the two. I haven't tried to split it more than once, though I probably can. I like how it boots faster than Windows 7, wakes from sleep faster, wakes from hibernation faster, and so on and so on. I'm not upgrading my Windows 7 machines, but I am upgrading anything with Vista or XP. Windows 8 is great. I'm totally happy with it.
Well, the built-in Facebook app and mail apps aren't my favorites. That's mainly because Thunderbird and the web work much better.
