Yes, you have the desktop, for now, but again, Microsoft has made it clear they consider the desktop legacy. How long until they remove the desktop altogether?
Microsoft as much as people want to say that Microsoft said this they haven't, in fact they have said the complete opposite:
We do not view the desktop as a mode, legacy or otherwiseit is simply a paradigm for working that suits some people and specific apps. This is very much like the person who uses a mobile phone but really uses it for the mobile browser and mail client and rarely uses apps or the phone. It is like the person who has a brand new tablet but only uses the web browser.
It would make ZERO sense for Microsoft to ever give up the desktop, it's their greatest asset and will be a tremendous one for years to come. The bottom line is that Microsoft did try a desktop Tablet PC and no one wrote touch apps. And while I myself don't necessarily like the a single source app store in this competitive environment in the age of the iPad, letting a whole new UI paradigm just go willy nilly has a lot of problems when it comes to quality control. If Metro apps ended up being nothing but malware filled turds, Windows 8 would without question fail on tablets.
