After over a year with Windows 8 this still bugs me every day...
if you want to kill aero that's fine with me, just keep it consistent
looks like it's going to be like this in windows 8.1 as well
Also, please dear god remove these ugly and fat scroll bars. People who use mouse+keyboard use the scroll wheel and people using touch scroll by dragging the content area. Thin, fading scroll bars like on iOS and Android would be way better.
