I like having command and control. I get Emacs-like navigation in every text box without giving up Cmd-[aefbnpt] for other things like select all, new tab or window, find in page, etc.

I don't use Spaces because it falls short of what I got used to on Linux, but not having a keyboard shortcut for that would be annoying. Perhaps SizeUp or Divvy supports Spaces, I picked up both of those apps this year and can't imagine living without them now.
