So you can somehow sum up an entire market based on the sales of one singular device, without any information about the demographics using it or buying it? In addition to that, the iPhone is a massively popular product, but it isn't owned by everyone, and not everyone wants one, for the simple fact that it does not fit their needs.
A family of five all need phones. If all companies go for a one size fits all product that is the same as a current high-end smartphone, then it'd basically bring you to 5*£450 (£2200) or whatever the contracts cost, which is way more than the average family can afford to spend on phones, and would you trust a 10 year old with something worth £450? I certainly wouldn't, and neither would most normal parents, yet that ten year old still needs a phone for getting to school and back.
To suggest that everyone can survive with something made for a one size model is totally obnoxious and ignorant of the needs of others, just because you are in the target market of a one size product, does not mean that someone with chronic eye problems can survive with it, or parents can risk it for a ten year old kid who has to travel several km to get to school or poor people, those on benefits, or the elderly can afford it. You're merely saying "it's popular therefore it's got the entire market covered", when it clearly hasn't, or we wouldn't have things specifically designed for niche markets. It's basically the same as saying "the Ford Focus clearly covers everyone as they sell well". Sure they sell well, but that does not mean that it covers what everyone needs.
Well they do have to many models, so no one recognizes or keeps track of them. Why not just say, 3 levels (entree, midrange, high end), with very memorable names rather than something that sounds like a name generator made them?
Edited:
And here I am, still saving for a Galaxy Nexus (which would be my first Android device) :(
I have that phone, the battery life is really bad, I heard it was the worst of all smartphones actually.
