Enable the location bar in nautilus ubuntu's file browser.

The more and more I sit with Ubuntu I find myself in gconf-editor doing things, whether it's adding the week to the time (handy in European workplaces), making the minimize maximize and close buttons sit in the correct corner with the correct order, or in this case get that location bar back.

So the steps:

$ gconf-editor

apps->nautilus->preferences->always_use_location_entry

You could do this in one line, but I'm sure there's a few other things in gconf-editor that will keep you busy.
