BTW, by posting that link I don't mean to suggest that Win8 is perfect or you can't complain about something being non-obvious in an interface, just that the "haha, it's not intuitive! therefore it's badly designed, this proves it! end of discussion!" "argument" is lame.
Windows 8 in corporate environments is already being received far much worse than Vista. Have a look at the comments http://windowsteamblog.com/windows/b/business/archive/2012/08/01/what-windows-8-rtm-means-for-businesses.aspx
There is not a single business of any size that would move to Windows 8, because of the "trifles" you are describing.
If Windows 8 takes off big time in the corporate world, I will eat my shorts.
