I think a more proper way of saying it, to me, is that "how the time is spent."

Spending 1 hour digging around the root cause of a failing driver is more interesting to a geek than spending 10 seconds closing windows.

Besides, if someone is experienced in a certain distro of a free OS, then it won't take too much time to setup his/her environment. I put most of my config files on Google Drive and it would just take me several minutes to setup my xmonad + vim environment.
