I just saw the news from Apple's media event that the new iPhone 6 will have 1.5 micron pixels. Here's a quick diagram showing the relative size of the iPhone pixel compared to a LS911 pixel.
I'm very impressed with what Apple is doing compared to traditional camera companies. And iPhone photos look really good. But, size does matter. We enjoy big pixels and big sensors when possible.
