In addition to the spacebar issue, the fact that the rows aren’t shifted, which by row 3 means the Z is below the Q instead of below the W, will make your brain melt.
Many handheld devices in the age of physical keyboards used grid aligned qwerty keyboards, so it's not unique here.
I think you mean "ortholinear". But yeah, I use a 4x12 ortholinear as by primary keyboard. Took a week or two to get used to, but I prefer this alignment to the usual staggered one now. With staggered rows I always felt like I was kind of guessing where certain keys were. Now every key is either under one of my fingers' resting position, or one key away from one (if you count diagonals as one key distance for tab/return).
