I bought a PFU Happy Hacking Keyboard Pro 2 about 14 years ago and that’s what I am still using to this day. I did buy a another HHKB Hybrid Type-S a few months ago for my work setup though.
10-15 years ago I was big into keyboards. I even designed (PCB, case, etc) a custom 40% keyboard back then. The HHKB killed the hobby for me. It is surprisingly durable and by now I’m much slower on bigger keyboards. I honestly see myself using this till I die. At least this specific physical layout and mapping.
For some reason that doesn’t work for me when I am offline.
