I've observed my parents, wife and sister using OS X and they've NEVER ever quit an application "the Mac way". They just click the red cross and think that quits the application as it does on windows. The only person who gets upset about their behavior above is me and with this change, even I don't need to bother. I think it's a change for the better. The policy for automatic termination is VERY conservative so I doubt an application will be terminated when you really don't want it to.
