Say what you want about Ballmer, but the man is more colorful and more of a clown than Bill Gates ever was. See his now classic : MONKEY DANCE:

The casual email or web page user might adapt easily to Win8, but hardcore user, used to multi-tasking on multiple screens will resist.
My main complaint with the Release Preview is that I need to concentrate on the software development or system administration tasks at hand, and not have to think about the UI components that support them. I typically have 2 24” monitors, with 15 - 20 windows open that I’m switching between. Win8 does not seem conducive to this.
