Good products "for people with disabilities" are often just good products full stop.
Take for example Good Grips[1], a brand of cookware and kitchen tools. Initially designed as specifically for the elderly and people who otherwise have trouble gripping conventional kitchen utensils, it's become a bestselling brand in its own right (I own several things) because the products are just that much more ergonomic and sturdy than anything else.
Some other recent HN article did an interesting presentation on the reason so many Infomercials for products seem so weird is that the only way to sell some of these products designed specifically to help the differently enabled have to be sold as if they were for particularly lazy fully capable humans. In order to try to get the product to market at all, they have to market to the weird/lazy/strange mainstream target market you see in Infomercial pitches, and often you miss that little bit of "originally built to help my elderly friends or invented to help someone after a stroke".
