Currently there is no way to uninstall Apple updates, correct? This should have been in OS X 10.0. It's a pretty big gaffe. Sometimes updates have egregious effects, even from Apple. XP can roll back updates. So why can't OS X, even 10.4? I sure hope they add this to 10.5. Then they won't have to, for example, post QuickTime 7.0.1 re-installers. Shouldn't there simply be a button in Software Update that lists all the updates, with an Uninstall button next to each one?
