yeah, that's true. but I would say with dev tools and such, people might easily fork over $10 if they think it's nice
I'd say the whole "lower cost" thing is less of a problem when it comes to ergonomics, we know that many devs buy all kinds of fancy split keyboards and things like that to make their workflow smoother, so I wouldn't be surprised if people easily forked over money to this
question is if it will actually take off or actually provide/slot into workflows that people actually like etc. if it's heavily opinionated or not really innovative, I don't see how people would "move over"
just my take though.
Absolutely, ergonomics is a huge part of the value- it solves a real problem.
