I get exasperated that you still can't properly disable browser-type windows in the OS X Finder. Yes, you can press cmd-option-T to "Hide Toolbar", but 1 in 10 new windows still appears with the browser appearance - network drives, USB sticks, something you've unzipped, or just randomly because Finder feels like it.

I miss the whole spatial Finder, but if Apple could just give me an option for "no browser windows, ever", that would solve 80% of my angst. (Well, Finder-related angst, at any rate.)
