At the risk of stating the obvious, it's easier to market one device, with a name people can remember (yes, 'iPhone' will do nicely...) rather than a string of meaningless letters (like most other phone manufacturers). I hope Apple produce a small suite of models, at some point, with and without particular features to hit a range of price points... but I don't understand why a company like Nokia always seems to have a couple of dozen models to choose from. Too much choice can be counter-productive... well, it is for me. Give me a choice between iPhone, iPhone Basic and iPhone Luxury, and I'll make a considered choice. Give me too many choices... and all I get is a headache. Of course, being in UK, all this is hyperthetical.
