The thing is, noobs shouldn't touch that settings. Not becaue it makes "senior members" (or just "more linux-clever ones) annoyed, but because if you don't know what you're doing, you may (almost) brick your device. This is not like on Android phones, this is Linux phone which is more open - that has positive aspects, but also negative sides. By negative I mean that when you take any two N900s in your hands, you may have totally different root filesystems on them and they may react in totally different way to your actions (editing critical system files). You need this very basic knowledge not to totally mess up your device... I understand this may be a bit of rocket science at first for someone who is not IT-related-guy, but you just SHOULD know that to use this device, sorry... you know how to do basic things on your Windows PC (/MacOS Mac) and you had to learn how basic stuff works, by the same rule you should learn dos-and-don'ts of Maemo system.
