Not being able to use metro apps in resizable windows is also easy to overcome: I don't use any of them, ever (and haven't found a single one I'd really would want to use).
This approach together with Classic Shell gives me a great and fast system that looks good and works as I want it to work. If the whole Metro part would vanish tomorrow, I wouldn't even notice.
The underlying tech is good.
Mictrosoft is just too big and clumsy to realize that they had a winner if they would leave people alone and let them work the way THEY want instead of how some Microsoft Hotshot imagines the future.
Cheers!
