I feel it’s different to taking photos on film rather than your phone. (Both of which I enjoy.)
If I wanted that stripped down to the basics writing experience, I’d rather get a mechanical typewriter than a computer which has been deliberately limited to act a bit like a typewriter. There’s something in the experience of the physicality of tools which demands physical tools, rather than emulations of them.
I know the writer deck isn’t exactly a typewriter emulator as such. I’ve looked at several similar devices on the market, and they’re a bit pricey for taking a punt on.
