It strikes me as a terrible stroke of stupidity to try and blend a tablet interface into what is primarily a desktop OS for the majority using it. I mean, even Apple keeps these separate, OSX looks a lot different to iOS.
Not to mention the fact they put the whole Metro on the server aswell. If I didn't know better I'd swear Microsoft is out to destroy themselves.
8.1 helps somewhat but it doesn't seem to address what people are mostly complaining about. Shame, because I gather under the hood it's a good bit better and more lightweight than Windows 7.
