There is
nothing special about Linux
Seriously, think of it as just a different operating system with a different front end, not so different from the Wii, PS3, or XBox360.
Except that on the Wii, PS3, and 360, the systems actually cut off your options to do extra things unless you do want to get complicated, whereas on PC-style OSes like Windows and Linux, you can go as far as you like, without anything acting counter to your actions.
