I’ve been using my Model 01 since October (2017), having just received my other two last month, or the month before. Yes, I have three Model 01s.
It is currently the best keyboard on the planet. Until J + K decide on Model 11, I have no complaints, of course we all have minor wishes, features, etc. but taken as a whole, the design + program-ability of the M01, its difficult to imagine a better keyboard.
It is extremely comfortable to type on, so much that I really have no need to leave (a rather outdated) QWERTY. The physical layout + multiple layers practically solve any RSI issues. Two of the main reasons not to leave QWERTY are: 1) moving to a qwerty kb (on someone else’s machine) becomes a hassle if I’m using/learning dvorak, colemak, workman, etc.; and 2) the ergo (non-ergo) issues have mainly be solved with the design of the M01, + I like not having to remap and relearn crucial functions (namely copy/cut/paste, ctrl-c, -x, -v).
All the cool things people have added, whether aesthetic or functional is just icing on the cake.
Thanks J+K and everyone else.
