Look, as a sysadmin I can tell you that it isn't just "change" that makes me dislike Windows 8. Setting this thing up for a user's desktop is a grade-A class 1 pain in the ass. I finally got an image that at *least* keeps all the standard shortcuts and displays them in Metro across all profile, but if I install something else it doesn't show up at all until I get the user logged in and step them through how to sticky it in the Metro list. And the only way to do that for them is in the base image when you sysprep it.
Now, yes, people can figure out how to sticky their apps, but it's a retraining issue and it just flat out gets in the way of them doing their job. If they'd just kept the damn start menu I wouldn't be complaining (even if it needed a reg-hack to enable), but instead they're forcing this cruft down our throats, and as enterprise users we don't appreciate it.
For the home user it's actually pretty close to ideal. You can spend most of your time in "tablet mode" and sit their consuming content and writing the occasional document or Facebook update. You don't need anything remotely related to added complexity. Fine. And Microsoft's overarching goal of getting people used to the UI so they'll be more apt to buy a WinPhone? Sure, I get it. But alienating corporate customers in the process? That's just shooting yourself in the foot. At least the Enterprise Edition should have a more serious interface.
