This is a quarter measure.. towards a tented split keyboard..
As far as FLAT layouts could be done, this board does mostly right in that regard.
/Larger thumb keys
/Columnar alphabet keys
The one issue however, is that the keys fan out.. at the top, that seems like an odd choice, because your fingers do not become narrow as they close. it's a straight line.
I'm not sure why this fan approach is being used.
I believe they're incorrectly tracing the finger path based on a GRIP motion.
where you'd spread your fingers while going from a grip-extension into a fist.
When you type that does not happen, one does not naturally extend their fingers laterally if they're not trying to grasp at something..
