If Apple were to do this, it'd make it even harder to switch to the Mac when you have iTunes (iPhone, iPod support), Safari, Quicktime, and iChat running cross platform.
Very, very true. But in the end you still have to deal with ::shudder:: My Computer and Control Panels. As long as Apple doesn't give them Time Machine, there's still something to be desired.
I'm still wondering why Apple isn't creating iChat for the iPhone. AIM is there, so what gives?
