If anyone had actually spent time using it, or if CowboyNeal was attempting anything other than a flamefest to drive ad impressions, perhaps that'd be more clear to people.
Imagine Windows 7 where the start menu opened at login and took up the whole screen. That's it. If you don't use any modern apps, you won't ever see the WinRT part of the system. Start an application, you're on the desktop.
Simple question: Do you use Metro IE or desktop IE?
I'm trying to run Win8, and when I'm living on the desktop I'm okay. But then I try to open up a PDF, media file or image and suddenly the default Metro-based app launches and my desktop and task bar are gone. I haven't yet figured out how to close the Metro app to return to the desktop. I have to alt-tab back to the desktop and then right click in the top-left hotspot to close the Metro app. Instead I am now manually dragging PDFs into Chrome (the desktop version) and right-clicking media files to launch in desktop WMP. (Adobe's PDF reader annoys me, too, so far I am avoiding installing it.)
I've installed Win8 on my main home machine to force myself to get used to it, but I have yet to like anything about Metro. Shutting down or sleeping the computer takes several gestures and clicks.
When I look at the Metro screen my brain wants to explode. The Win7 start menu does a decent job of promoting my commonly used links while allowing me to pin items if I want, but I can also search the start menu, and unlike Metro it will show me apps, files and control panel items in the search results. In Metro I have to move the mouse a lot and click to search files, apps or control panel items. In the Win7 menu I have the option of browsing the hierarchical folder structure, too. In Metro I get the mass of gaudy tiles that make no immediate sense to me and then a bunch of ugly tiles for installed programs and all the items that might have appeared buried in the hierarchy in Win7. I am not liking it yet and haven't yet figured out an advantage for me with Metro.
