A wearable option: As for hardware changes, I believe a wearable, wristband-type device would be a great complement to the iPhone, in terms of accessibility. Because of my cerebral palsy, there are times when holding my phone is hard. I sometimes find myself in situations (like the grocery store) where I need to act on an important message, but my hands are full and I can't comfortably reach for my phone. A wristband device could allow me to tap a button to read a message and then use (a working version of) Siri to act on it. Rather than just being cool toys, wearable devices could have a major role in enhancing the iPhone's accessibility appeal.
