I'm trying to setup a *buntu system for grandma. Her needs are a browser, a text processer (libreoffice will be fine), being able to watch youtube and not being able to get into too much trouble deleting or misplacing files that she really would rather keep.

Is there one of the ubuntu variants that makes it easy to set this up (edubuntu?) Or should one stick with the stock ubuntu (since I have only really experience with that) and then remove all superfluous menus etc.
