Interesting read. Although, at times it seemed like there was an over exaggerated response to metro design.
I agree though, that Windows 8 has, by default, split into two operating environments. It's not contingeous anymore. I have to configure the Start Screen and get rid of some metro apps so I can work with it on a desktop. I'd rather see Windows 8 adapt to the desktop, and not try to make it more touchy when it's not. I'd rather see Windows 8 adapt itself to a tablet by making use of the metro design, apps, and Start Screen. I don't want to see become an operating system with two identities on one device, pick one and adapt the other I say.
