I thought for the first time that I'd stay on the cuttng edge of Mac OS. Little did I know that under Tiger all of my applications would crash more often and run more slowly. I also didn't know that Symantec wouldn't support Tiger, so that my old versions of Norton Utilities and Norton Antivirus no longer work while Symantec does not plan to sell versions that do work on Tiger.Both my classic applications and my OS X applications run slower and crash more often. I really regret upgrading. Sure, the widgets function is nice, but not worth the trouble Tiger has caused me.
