The strange thing to me was the choice to use a 1.5x key for the right arrow, left alt, and circle keys. All would benefit from leaving a small gap at the edge of the row to navigate to the corners by feel. The alt key being the same size as the two keys around it also make it harder to sense by feel.
I sometimes struggle to hit the backspace or enter keys
correctly, but probably will adapt over time.
I could do without the delete key or the function keys...
Nothing is really a deal breaker!
