I am going to have to download this and give it a try before I dis it - actually I may do that retrospectively and dis it now instead.
So long as they keep selling Windows 7 side-by-side with Windows 8 then we'll all be okay.
Maybe, just maybe, what we're being shown is the home user version of Windows 8. . .There's a Windows 8 Professional version aimed at business users, right? Well, since nothing that you'd expect to run in Metro has any place in a business environment, logically Metro will be hidden away. I mean, if someday I have a Windows 8 PC forced on me at work, if the boss looks over my shoulder and sees absolutely any Metro app running, he'll know I'm playing instead of doing my job.
Edit: So I installed Win 8 preview on my laptop to play with, I'll keep this brief because the obvious things have been said many times already. So far the normal Windows desktop stuff looks fine - everything works, some nice touches on the new things. No complaints.
I've played with the Metro apps now - their primary purpose seems to be to try and sell me new things instead of helping me navigate the things I already have. Most of the screen is taken up with big pictures of things I can buy, while navigating the things on my hard drive is quite difficult. Copied my music folder over to try things out. . . navigation was not pleasant. Similarly I thought XBox Companion looked promising - you can trigger your XBox to start up and run a game, but only if its one of the few most recently played. . .can't seem to browse the games I have installed. I can however "Explore the Game Marketplace" to buy new things.
Metro apps in general are confusing. There doesn't seem to be a common interface between apps - I keep getting random menus pop up when I point in different places, and quite a few times I've accidentally made something appear for a moment and then been unable to find what arcane movements made it appear.
I suspected it before, but now I've used it I can say it with some conviction; None of this Metro stuff belongs on a desktop PC.
