R34P3R: Yes, your point holds true. However, I very much doubt that many are going to be considering either a San Fran or an iPhone. They will be comparing similarly priced phones. When talking about the iPhone, most will be talking about iOS, not the hardware.
When it comes to the pricing and generations of a device, it simply isn't about whether it is enough; at the end of the day, if the hardware has moved on, the phone is last generation, so the pricing so change as a result. The value of the infrastructure could easily be argued to be the choice of the consumer, not the manufacturer. At the end of the day, Android works better for some than iOS, and vice versa. Yes, the iPhone in its current form runs well, but so does my DHD, and I'm not paying extra for that, am I?
Just thought I'd also say, the reason that the SGS2 runs well isn't because of the dual core processor; it is all down to the coding. My DHD running CM7 honestly runs just as smoothly; TouchWiz is pretty light. And the scrolling is not particularly natural, so you could say it is a bit of an animation in a way.
