there's a big market for "makes your life easier" tools both in B2C and B2B
maybe not that big of a market but who knows
Note, I am deliberately using a generic example, I use Ghostty but I haven't tried Rex yet and I have no idea how much value it provides over competing widgets)
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.
