Then margin on Macintosh hardware is notorious for being slim. Where it seems they make their money is in the options for more RAM and larger storage. But Apple doesn't make much profit on the base configurations of any Mac, and until they started charging a premium for more RAM or storage, Apple didn't make much profit on any Mac configuration. Apple's history bears this out, as Apple only started growing wildly with the introduction of iPod and iTunes Store, and again with the introduction of iPhone and iPad.
