I hate to say this, it's like I'm stabbing my eyes out when I say this, but Windows 8 and the Do Not Track options in IE10 is having me switch slowly over to IE for browsing. I open the new Chrome and I open the IE10 in Win8 (not in Metro mode) and it's just so much faster. The optimizations with IE10 and Win 8 are really apparent.
I like Windows 8, and tbh if you don't want to use the tiles on the start, don't. For me, it comes up in the beginning, I hit the tile for the desktop and I rarely see it. You shouldn't really have any compatibility problems aside from some very old legacy devices.
