I mean, I used to like typewriters like these, and used them a fair bit. But ... wow. And actually using the carriage return (NOW you know why it's called that!) for enter?
Even considering someone who's a "retro lover," I can't help but think these would be hugely impractical. Maybe a few "steampunk computer desks" will have them (and probably with a nice, real keyboard tucked away somewhere.)
It's different. I'll give it that, and good work to the people who got this to work. I'd say it's pretty much the definition of "niche market," though.
