While I agree with your overall point here, I just want to point out that this is just a form of a huge concentration of anecdotal evidence, not a true substitute for quantifiable evidence. While you may deal with disabled people 40 - 50 hours per week, that still does not mean that it is a representative sample. For example, if everyone you deal with are highly experienced computer users, and the overall population of disabled people are extremely inexperienced users, your personal experiences are not applicable to the population as a whole.

Again, I agree with the overall point that you made. :)
