I'm probably going to be exiled from the Maemo/Linux community for this post, but here it goes. Ideally, you should never have to go into the command line for any system or application settings (the only exceptions I can think of is writing scripts) Firstly, it's not user friendly and is going to turn off 80% of non-geeks. Secondly, there is no reason for it, not any that I can think of. If it's worth putting into the command line, it's worth putting a GUI on it. If a GUI is too much trouble, then have a kind of "system:config" page similar to the Firefox "about:config" page.
