I've been using it for about two months myself, and I have to say that I do see what Microsoft is trying to do with Windows 8, but I know that this process is going to lose them sales. The problem with Windows 8 isn't that it has a touch interface, or even that it employs full screen apps. The problem is that if you use it with a keyboard and mouse (as desktop users are wont to do) you have a lot less uasability with the OS. The abilities are there, just a lot more of a pain to find. It took over a month for me to even discover that you could close an app by draqging it to the bottom of the screen. I didn't learn it on my own either, I had to find a video online to even know it was an option on the touch side as well. That's where we find the issue, not only is Microsoft treating the enterprise users as second class citizens, they aren't teaching people how to use their interface which isn't the most self-explanatory interface I've ever used (I can usually figure out an Apple product pretty quickly, and there was no learning curve for me at all in Android if you want a basis for how I arrived at that conclusion).
Windows 8 isn't the worst OS I've ever used, but it needs a lot of work (one of which would be to re-instate the start button and boot into desktop mode for "power users" or people who are actually attempting to create as another poster said). I believe that once they release Windows 9, it'll be much better. Thus perpetuating the "Windows cycle."
