Don't like category view, never did. For me it always took longer to find things. And I also don't really like the start screen. Biggest thorn in my side with it is settings search. In Win 7 I can just type the name of the applet, like mouse, hit enter and I'm there. In 8 I have to type it, arrow down to get to settings and then click mouse, very cumbersome and annoying to do something that used to be so simple.
This is why I use Startisback on Windows 8
