All the programs that would be on the start menu are accessible via the metro screen as are My Documents, Devices and printers etc.
True, they are available.
If you're willing to scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll, scroll to get to them.
The truth is the Start Menu and Task Bar are very efficient ways to get to things quickly, particularly with nested folders in the Start Menu and the ability to pin documents as well as programs to the Task Bar (starting in W7) - everything is right there and compact and you don't have to move the mouse a mile to get to anything.
But I think one of the main problems is whether or not Metro is "nice" or "attractive" or "usable" or whatever, many people don't want to have to waste time learning a %#*&&@#*$ new interface when they already know the old one, which already worked very, very well for them.
I actually like the idea of one OS that could work well on tablets as well as conventional machines, but I think they made a mistake of compromising the conventional interface too much in the process. But again, installing Classic Shell fixes most of that.
