Of course it depends what kinds of programs you run. If you run a database, it can become corrupted to the point that you can't start it anymore, so you have to restore it from the latest backup. Been there, done that. Another example, this happened to a friend of mine: After a network outage his Opera browser didn't work anymore. He had to remove his ~/.opera directory to get it working again (and he lost all his settings). His home directory was "soft"-mounted, but he removed the soft option after that incident.
