I don’t know if you consider a single button a questionable decision, but the ADB II mouse was as close to perfect as the technology was able to support when it was released.

I've seen this behavior in people that have seen other people use mouses for over a decade before, especially my Mom. It's my personal universal sign to immediately stop teaching that person anything. If you get shown a mouse move across a table like a pug, get explained that moving it up and down, left and right is a relative motion and you pick it up and wave it in the air you are just signaling that you do not want to learn.

My mom and her friends pestered me for years as a teen to show them how computers work and how to use them. When I tried to teach them the basics they were dismissive as if the computer had to conform to their way of thinking how the interaction should work. I learned to not engage with those people at all. Funnily enough, a decade later after they actually wanted to learn it they figured it out themselves.

Why would you buy a car that didn't have that, or better technology?

Hopefully VoiceInk gets there. It is a neat project and really well done for a first time dev but rough around the edges. Careless is ~20$ and if you just need dictation is the best option.
