I've just come across this wonderful article by a woman who is blind and deaf. Sounds like the Apple Watch is a really fantastic gadget for her. I'm a wheelchair user and will most certainly get one. It's good to know I can reach my husband when I have a fall, even without carrying around a phone. The thing is so much sexier than one of those emergency buttons and I'm sure many people with disabilities will find great uses for the Apple Watch.
