@m3tti I would probably still be using an x61 if it had an LED backlight; that's kind of a requirement for outdoor hacking.
been meaning to look into those aftermarket kits from Shenzhen https://geoff.greer.fm/2017/07/16/thinkpad-x62/
@vaer_k there have only been a handful of studies on the topic that attempted any level of rigor, but I think they all were pretty seriously flawed.
my experience has been that the speed improvements tend to be overstated, but the comfort improvements have been very noticeable for me. but having to spend a couple weeks of being borderline useless at typing is rough.
also I don't think dvorak has any advantages over colemak, which is what I would learn if I were starting over today.
@vaer_k I hear ya.
IMO changing your physical keyboard layout is a bigger win than changing the logical layout tho, especially for emacs users like myself who need modifier keys to be on the thumbs
@vaer_k sure; the one I made is at https://atreus.technomancy.us and it's the most portable option that's still comfortable
other good choices include the Iris, the Ergodox, and keyboard.io
