You know, I have tried... And I really, REALLY tried. I installed the Release Preview this morning, and saw that nothing much changed.
I installed the Release Preview this morning in hopes of "controlling" the new dual UI experience in such a way that, all the apps that I used to use on the desktop would be kept that way, while I'd use Metro for more social and "fancy" apps such as Messages, People, SkyDrive and Weather (Xbox not being available in my region right now).
But the problem with this is still big, much too big to describe it all because... well, I don't have the patience. The Metro UI is still clunky, it still looks too primitive and ugly to me, navigation is clumsy and the options are pretty bare and poor; in most cases, for what I wished to do with those apps, even nonexistant.
What I did like in Win8 is the new Aero look; I'm not drooling over it, but getting used to the (IMHO) disaster of the Win7 Aero look prepared me for it pretty good, and I got used to it pretty quick. Also, much of the desktop UI options from Win7 are just missing or completely (dis)placed deep inside the Explorer's Ribbon nightmare. I also immediately fell in love with IE10, and didn't even for a second bother to consider a secondary browser; but that's pretty much it for Win8.
Congrats on MS for their efforts, but I'm going back to Vista until such a time IE10 comes out, at which point I will probably just go back to Win7 (seeing as how stories tell that IE10 won't be available for Vista

)
