I hate the tiny key travel, flat keycaps, removal of pgup/down/ins/del, and putting the function keys as secondary functions of media keys I never use.

> We have no mechanical challenges now, but still using misaligned, less usable keyboards, why?

Inertia. And I have trouble finding an intuitive reason why an aligned grid would make typing easier; just sounds like something slightly different for my muscle memory to adjust to. I can imagine something like the combination of aligned keys spread into a slight arc shape being nicer, just because of the angles involved.

Grid is a bit more intuitive for me, i am not sure how curves and arcs will do for me, grid is really easy mental map, befor this grid keyboard i was not 10-finger typist, now i am, even on regular keyboards.

Biggest downside of regular keyboard - spacebar lots of useless space, put 5 buttons instead of one, your thumb can push a lot of buttons while other fingers do not leave home row, make 2 of them space, shift, ctrl, backspace buttons under your thumb. This is main reason ErgoDox or Kinesis are good, and regular backspace and return key position sucks, keeping index finger on J while pressing Backspace with pinky is a challenge that moves your palm.
