Windows 8 consumer preview

Why did I download this? I can't even work out how to turn my computer off anymore.

A couple other things I forgot to add:
-better hardware detection right off the bat
-no start menu? wat
-the squarish theme looks nicer than the overly-rounded default Win7 theme, but I just installed a Win8 theme for my Win7 install
-ribbon menus are shit, stop fucking with explorer
-new task manager and resource monitors are really cool
