Features on devices meant for people "with disabilities" (can't they just be honest and say for blind people?) should not be turned on by default on devices used by those without said disabilities. When a person "with disabilities" gets a new device, chances are they aren't the ones to set it up because of those same disabilities. As such, the person setting it up (usually a phone company employee or retail clerk with the right experience or training) can turn those features on as they enable the device for use.

The idea that we ALL should have devices meant for the lowest common capability is downright insulting. We can be equal in shared respect while at the same time acknowledging openly that we are not equal in capability.
