I am a new mac user with a macbook. I had a problem in the first couple of days where I changed the name of my home folder not thinking that it would basically "hide" all of the music and such that I dragged over from my old windows machine. I ended up having to reinstall OSX because I couldnt figure out how to get it all going again. There have been a few occasions where I accidentily drag my home folder outside of the HD folder. Luckily I notice it and prevent erasing it from the HD folder (this is really easy to do with the trackpad on the macbook). What would have happened if I accidentily drag my home folder, app folder, or whatever outside of the HD folder...would everything disappear again? If so, dont you think that makes OSX a little "too easy" to screw up if you are like me and dont really know what your doing yet. I say this because I am strongly considering getting a mac for my desktop system and dont want my girlfriend accidentally screwing the account up by renaming a folder or dragging a folder outside of where it is supposed to be.
