Apple products all have a built-in accessibility function in them, so this allows people with disabilities to use technology. The accessibility features are free, with no cost involved when you purchase an Apple product. These features can include, VoiceOver, a screen-access technology, for the blind and visually impaired, computer voice to assist the disabled users.
As a community, we are not being use to its accessibility being a part of the development of product, we are use to it being a after thought, side bar or an add-on. Apple products are the only and first device to come up with such ideas to allow disable users to gain access to these technologies.
From this, I believe Apple is not only the dominating firm in its market but also building its brand image and reputation by acting more ethically. By investing in features to allow their technology accessible to everyone, or at least most people as possible. I believe, this would allow Apple to gain an extra market segment which other competitors don’t have and Apple will have a slight advantage over others as it continues to develop with such attitude.
