According to wikipedia there are an estimated 40 million blind people in the entire world. If we assume a global population of 6 billion, that's 0.007% of people. And a large portion of those people live in a state of poverty. So, not a very big market. Doesn't seem worthwhile unless you can get governments or private charities to give you money to develop it.

What happens is that there are companies that will work on products like that, and then they will go on to sell said product for hundreds if not thousands of dollars (if not more) to justify the cost of designing and producing the product. On the other hand, voiceover comes with all iPhone 3GSes and voiceover on Mac OS X is free and comes built into the OS (even during OS installs!). I guess that's Apple's way of telling blind people that Apple doesn't care about them and they should go buy other products..

aging population throughout the developed world == rich blind old ppl. i've seen simplified mobiles (look and work like a cordless home phone) in japan aimed squarely at this growing market.

  A key point buried here: the aging population cannot use iPhones because the fonts are too small. Give an iPhone to someone older who needs reading glasses, as I have (with my parents, in-laws). I find they understand the natural affordances of the iPhone interface pretty quickly, which is a testament to the good job Apple did there, but they often just cannot read the screen.

    That's a separate problem from adding accessibility for blind people. The obvious ways to make touchscreen phones easier for old people are larger buttons and text, and exaggerated visual cues, which help blind people not at all.

I think you mean 0.7% of people, which is not necessarily a small market. Developing a sophisticated consumer electronics product like the iphone may be expensive, but developing a few software apps for it isn't necessarily, especially if you can dominate the market for the accessible phone. That said, I would agree that there are more compelling markets out there. I wouldn't be surprised if most accessibility developers have altruistic motives.

  If it makes commercial sense, you don't have to legislate for it.
