Apple doesn't do cheap low end mass market. Their target market is always high priced early adopters. (Which is all too often usually smug bastards who want to wave their latest shiny shiny in your face to say hey look at me, they have it and you don't. Dyson are playing to the same market with their products. Some car companies do the same thing, but the problem Apple have is that their technology driven markets suffer obsolescence very quickly. People always need vacuum cleaners and cars, but phones and computers etc.. become old very quickly).

Therefore Apple do get good early growth figures in a new market, but over time, they cannot compete as price cuts reduce profit margins on newer phones and computers etc... Its at that point companies like Apple have to reinvent themselves and target new markets. e.g. from Macs to ipod, iphone, ipad.
