Any machine without software is just a huge pile of metal, plastic and other materials. Operating Systems, huge and complex applications, but also small and cute ones, will all find a place here. Of course, I mean the free ones. You might be skeptical, so was I, but it has been proven several times that you can use any IT related machine, without even touching a software that costs money.
