I agree, but it's not want Apple wants to communicate, obviously. If they are going to use plastic in iPhones in the future, they want to make it appear something "high grade" now. :) So they have to strike the iPhone 5 in the lineup. Ha! Funny Apple... Not really. Also if they did 5 -- 5c -- 5s, naming would be confusing, because it would seem iPhone 5 with no letter added is the low tier -- crazy, yes, but people would see it like that.
