I think it slightly disingenuous to just pretend that big honkin’ antenna isn’t there and then say “it’s the size of regular cellphones”. My Motorola Startac from 25-30 years ago didn’t have an antenna that big.
It’s 143mm x 55mm, the iPhone pro is 146.7 mm x 71.5 mm and the iPhone pro MAX is 160mm x 78 mm. Granted it’s also thicker and slightly heavier, but calling it cellphone sized is reasonable IMO.
