I don't think there is anything noobish or wrong in thinking of your computer as just a tool (not that you said that directly, but it could be inferenced). What is it, in the end? A tool for communication, development, research, whatever.

Some people just resist any kind of change - they're used to Windows, they aren't going to try anything else, because they think (and they might be right in theory) that they don't need anything else.
