Which is a real good idea.

Why? You just add another concept to learn, which many have problems with (although it *is* quite easy). And GC is the thing of the future, retain/release the past. Proof? Xcode uses GC, and since it does so, it became a lot more stable. I’d say this proves that GC is ready for prime time.
In the case you are forced later to use retain/release (working with old code, Tiger compatibility, iPhone development), it is still time to learn it then - after understanding how Cocoa works.

There’s comprehensive documentation by Apple about retain/release rules. If you really want to learn this now, read this documentation. And read it again until you really understand it. Guessing won’t work.
