It looks fascinating and will go to an Apple Store just to try it out :) but yeah substantial compromises have been made.
Regarding the Pro Max: I have a regular 17 Pro and find it a brick! Big and bulky, borderline usable one-handed. I cannot fathom carrying and using the Max size! I have fairly big hands, too. Maybe is the jump from the XS that makes everything feel cumbersome, that phone lies just perfectly in the hand…
