(2) Because data is immutable, there's a chance to share references. I'll mention strings again as an example. Two immutable strings that contain the same exact data could be stored such that only one copy of the data exists

I ran some tests a while back. On at least certain types of immutable foundation objects, -copy just returns a the same object with retainCount + 1.

In other words, it's not theoretical (since Evan was asking for hard data).
