Suggestion: State that Linux runs on PCs
Many people with whom I have spoken about computers are under the notion that the operating system is directly tied to the hardware that it runs on. In other words, they think that PCs only run the Windows operating systems and that computers manufactured by Apple only run the Macintosh operating systems. When you present them with a new operating system, such as Linux, they immediately think that they will have to go out and buy an entirely new computer to run this other OS.
I just thought that this might be something that needs to be explained on the get GNU/Linux Web site, but I could be wrong.
