While true for many Linux fans, the majority of regular Linux users, especially those in the enterprise arena, do not customize anything and simply use it the way it is installed/configured by default - pretty much as they would were they using Windows or MacOS.

I used to enjoy endless customizing (Enlightenment) but that ended up taking the place of actually doing work. These days I leave everything set to default and install as little software as I possibly can.
