Everyone is saying "just use the keyboard", but what about those of us who want to use the mouse? You know, that thing sitting on the side of the keyboard on desktops for the last twenty years? It seems that everyone who really likes Win 8 is saying "Ignore the GUI, use the command line" which kind of says it all about the quality of the GUI with regards to workflow and ease of use.
I mean really, trying to find a program that you want to run via a single mouse-click now involves keyboard shortcuts and text searches, remembering the exact executable name (rather than just having it presented to you), screen-fulls of unrelated metro icons to search through, etc.
It's just really clunky and off-putting to have to do so much work just to get to the point of running a program from an icon on your desktop.
What's worse, is it really wouldn't take much to fix, but MS seems to be ideologically fixed into this course of a touchscreen UI on the desktop.
