I appreciate what you're saying and felt the same until I got a closer view of W8 at CES in January. The Metro UI put me off when I first saw it but it's starting to grow on me. I like the simplicity of the icon-based app selector and the ability to provide some lightweight info in real-time on the icon (number of new email messages for example) is a nice touch.
But more importantly, I think where Microsoft is going with the W8 UI is smart because it was designed with smart phone and tablets in mind, so it will be possible to have a very similar if not identical UI across all hardware platforms that run W8 (desktops, ultrabooks, tablets, phones, etc.).
Like you, W7 has worked very well for me and I'm happy with it. However I do plan on finally catching up with the rest of the world and purchasing mobile products shortly after W8 is released (smart phone at minimum, probably a tablet too). From what I saw at CES W8 looked and worked well on mobile devices and though many in the tech media world have poo-pooed anything Windows phone to date, their critique may not be as relevant for W8. Throw in what I suspect will be tight Skype integration and Microsoft MAY have a competitive solution.
As for W8 and WMC, no one from Microsoft could-or would-tell me anything about it and no example was shown. Rumor has it that it's not going to change much from the current version running on W7 but at minimum, I really think they need to add much needed codec support to the app. I'm currently running W7 and JRiver Media Center and this combination works very well though I still have to use WMC for my Ceton cable card TV tuners.
