I hear what you guys are saying, but I stand by my original point:
All of these critiques are extreme exaggerated hyperbole designed to get them page views or whatever.
BUT, having said that -- I still can't help but agree that everything they are pointing out is in fact a user interface design flaw that represents a step backward.
I'm not saying that these flaws are the end of the world, but i am extremely perplexed at these things that seem like clear flaws to me.
Of course I could be wrong -- these could be masterful paradigm shifts in user interface design, but I don't see it.
At the end of the video he quotes a user interface pro (Budiu) making a comment that seemed on point:
"Windows 8 is optimized for content consumption rather than content production and multitasking. Whereas content consumption can easily be done on other media (tablets and phones), production and multitasking are still best suited for PCs. Windows 8 appears to ignore that."
More from her: here
I think that's a perceptive observation about this new user interface. It sacrifices desktop usability and content creation in favor of content consumption on a tablet. That's not so great if you want to use a desktop as a desktop.
I guess from my perspective, Windows 8 feels like a step in the wrong direction for desktops. I haven't heard or seen anything that would change my mind about that yet.
