To be honest, I think they've done a pretty good job of getting the touch support sorted while keeping the new stuff useful with a keyboard/mouse. Sure, they've got a long way to go but it's a good start IMO.
It's clearly not very popular though.
I think they could've mitigated a lot of the problems by having the default Start menu include shortcuts to Control Panel, My Computer, File Explorer; all of the usual desktop start menu "pinned" items. Then, a separate group pushing the some new Modern apps with their live tiles. At least this might have started the desktop crowd off on better footing (a "oo, what's that" rather than "why are they forcing this on us?"). And a power button on the start screen in addition to the charms menu button might've helped too
