I can see the case for and against the word "disabled." When you have a feature of a computer program disabled, that means it doesn't work. It's turned off. For purposes of that program, it might as well not exist. And that doesn't describe a human being who simply needs accommodations and/or assistance. I like the "people first" language, for the reasons lizardlady states. I, for one, am a person with several disabilities. Challenges, impairments, barriers, whatever you want to call them. But that doesn't mean, and oh boy howdy have I gone off about it, that I'm useless and can't make contributions to society.
