Also, regarding the someone hyperbolic grandparent post, iPhone will always have its place, just like Macs have survived nearly 30 years despite being the more tightly controlled platform. Likely (and hopefully), that niche will let them continue to do interesting, beautiful things, without ever coming close to dominating the market, which is a very scary prospect for fans of 'open'.

Also, in terms of the "dominant" platform, outside of the slightly-behind-the-mobile-times Silicon Valley, which seems to have only started noticing mobile phones with the iPhone, the dominant platform, by a long shot, is Java ME.
