Ok, this is exactly what I thought.
Well... first of all, if I use another user and I issue rm -rf * maybe I
will have a perfectly working laptop but without data! And for me data
are more important than a working system.

The problem is that there are a lot of reasons I won't use a user
instead of root, and I think that if root exist, it should e used. As in
my car I have the 1st gear, I can use it :-)

What about xhost?
There is a way to use the screen used by another user?
