somehow , i get the sneaking suspicion, that while not perfect, qwerty actually works on mobile phones because it’s focused on not conflicting keys when typing (so tapping with thumbs work /better/ because of this).

for example, "The quick brown fox jumps over the lazy dog.” — < means left hand, > means right hand. you can see in a common phrase like this, you alternate sides more often. when you’re thumb-tapping, i think this is useful.
