Earlier quoted context omitted.
On Linux if you learn shortcuts for close/minimise/maximise as well, you can even remove window borders and title bars entirely. It's free screen real estate.
The gnome window title bars are obnoxiously thick and useless by default tho. I've found that Unity or even just Windows like styling in Gnome is a lot more respectful to your screen real estate.
I wish it was simply configurable from the settings dialogs.
