Ahaha yes, and then you're left "only" with a few hours figuring out what broke in your setup because stuff like /usr/local was "liberally" modified by the update. Plus, of course, oops all your 32bit games are ded.

(Yeah sure, not your average Mac user, but still - don't discount the pain that any arbitrary update can and will inflict).

In my experience, updates have been completely painless to the point that at first you hardly notice you updated at all.
