I haven't used Win8, so maybe I'm completely off-base here, but from the article it sounds like removal of the Start Menu has made it difficult to do a lot of things without either typing in commands or memorizing special key combinations (see, for example, the section called "Run Power User or Administrative Tools - WinKey+X is EVERYTHING").
So, how does anyone get anything done using Win8 on a tablet that doesn't have a keyboard?
