I cannot agree with your more. In my 19 years of using Macs, I have had two problematic OS upgrades. The first was my upgrade to System 7.5. The one thing I hate about buying a new computer is moving my software from the old one to the new one. The notion of volunteering to go through that pain in anticipation of a once-in-a-decade problem strikes me as dumb.
What, you don't like that all new fresh and clean feeling?
