I agree, and also like that with Linux we can store all our settings
in /home and then reinstall an OS, without wiping those /home files
from our hard drives. Try doing that with a Windows reinstall. Windows
was always a pain to restore your Firefox and settings, bookmarks
etc., almost a game of musical chairs to find all the directories.

With the Linux file structure having a /home, it's not even scary to
test beta versions of Distros, as you won't have to bother restoring
your data between versions.
