It's all personal taste, but I think that the staggered layout of "normal" keyboards feels horrible. I mean we don't need to keep typewriter hammer arms from jamming any more :) It takes a while to get used to ortho but I find it much more comfortable
I love that I got to experience the computer revolution from (nearly) the start to its current state, but damn, I really do resent some of the bad habits I've picked up due to technical limitations that existed when I got started. I think ortho looks just so much better and more comfortable, but the typewriter layout is firmly engrained in my muscle memory...
The ergonomic keyboards I've seen still had offset keyboard rows, rather than the ortholinear setup shown in the tweet linked above. It's the uniform spacing and grid layout that I've never seen before (not to say that means its new; just new to me!).
Man, didn't expect to get my ass reamed for such a simple opinion lol. Personally speaking I feel like I'm more accurate and I have a better time finding where the keys are when touch typing.
