I like the Metro interface. I find launching apps off a fullscreen menu (known as the Start Screen) much easier than navigating the tiny Start Menus we had before. I highly doubt Microsoft will be returning to the Start Menu. The Start Screen is far superior and with some luck, 8.2 will include drag and drop support which is just about the only feature it lacks.
I also doubt we'll be seeing Windows 9 anytime soon since we're getting incremental updates every year. Fail to see how Windows 8 is a scam though. It works perfectly for me. As I said, once you've learned how to use it (put more than half an hour toying around and actually put some effort getting to grips with how the tablet and desktop interfaces work together), you find it actually isn't as bad as anybody is making out and if much much faster and more stable than Windows 7.
Honestly I don't have a massive problem with metro personally since I am used to it, but I think a lot of people feel they never asked for it and m$ wont listen to their concerns. And maybe they wont release a windows 9 any time soon but a lot of people are downgrading to windows 7 by buying retail copies of it. In fact just last week someone asked me to install windows 7 on her new laptop because she can't adapt to metro and is afraid to try downgrading herself. I also really don't like this dualism between desktop and metro apps, 8.1 made it easier to multitask but I still think they need to go back to drawing board, after all its a touch screen interface being run mostly on non touch screen devices, imagine if apple suddenly decided to have the same interface for ios and osx, the point is that the interface should be designed in a way that takes into account the method someone is using to control the system, for example to close an app in windows 8 you drag it down but a lot of laptops touchpads are not sensitive enough to drag it far enough, my own laptop and three others i have seen are like this. Sorry for the rather long post.
