I have been installing new distributions of SUSE every year or two. However, I found that if you partition your hard drive so you have one partiton as a /home to keep your data in, and do not overwrite or format that partition you can upgrade from one distribution to another and not loose your data.
(From Suse 9.1 to Suse 10.0, or from SUSE to Ubuntu, or come back form Ubuntu to SUSE).
When I attempted to share the home partiton between two seperate distributions, the computer sort of went nuts...

It seems like over the past ten years you've had much more luck than
brains... Time you started pushing the balance towards brains.
To run as root is the first impulse of a newbie who notices, for sake
of an example, that he can't access his cd-writer as a normal user. The
newbie usually also doesn't know, or bother to find out, that it's
possible to selectively or generally allow access to almost anything he
needs. So he continues running as root, asking for trouble. That you
have managed to keep it up for so long without any major damage is a
mystery to me. Are you sure really nothing happened - mind you, having
to re-install the OS every now and then may be normal practice for
other OSes, with GNU/Linux it is a doubleplusungood thing to happen.
Running as non-root simply reduces the damage any of the possible
factors - programming errors, the net and last but not least, yourself
- can cause. Try to delete important files as a normal user and you
will fail, as root, you will not. Reducing the level of access to your
system is a very effective safety net, and - contrary to other OSes
already mentioned - it also doesn't cripple your system. So there's no
reason not to use it.
