I agree 100% that the idea of Metro style apps with their severe limitations (on multitasking and otherwise) replacing desktop apps is a bad joke. However, I don't really interpret them as replacements, but just as another model with its own advantages ( isolation, suspension/controlled backgrounding, guaranteed declarative install) and disadvantages (multitasking limitations, walled garden, etc.) I think it's very stupid that metro style apps are set as the default for file types and on the start screen etc. However, as a supplement to the desktop I like having them available.
