I guess you're not being sarcastic. The iPhone was perhaps the only line without a entry-level component: the plethora of iMacs, iPods, and iBooks each had expensive/professional and entry/cheap lines, if not more than two. And even then, Apple typically left the previous iPhone model around at a discount so price-sensitive consumers could buy a discounted 4S instead of a cutting-edge 5, for example.
