@dyret:  Let me give you another perspective.  I work in corporate I.T. and we don’t upgrade to the latest O/S at least until the first service pack or fix patch has been released.

 Why do we do that? Because we need time to test and make sure the latest O/S is compatible with all the software that we run.

Regardless if I'm upgrading 1 PC or 100 PC's its the same principle.

You take a risk when you upgrade to the latest, which by the way is not necessarily the greatest.

I doubt any Graphics or Illustration companys are running out right now upgrading to LION.
