Did you forget large touchscreen, no physical buttons and no need for stylus?
Of course other phones had browsers, they were just pain to use and iPhone was revolutionary device compared to even most feature rich flagship device. It’s an opinion you may disagree with, but you’re in minority.
I don't argue that iPhone was revolutionary although I think it was way less revolutionary than average consumer thinks. I argue with very specific claim. OP have claimed that "being able to use a browser anywhere was the killer feature" and it is just not true because most of the market could do it. All symbian, blackberry and Windows Mobile phones could do it.

iPhones did have physical home button and O2 XDA II from 2003 has the same touchscreens size as original iPhone. Also you are forgetting that first capacitive touchscreens were awful. Qwerty keyboard or resistive touchscreen were just nicer to use. And you didn't have to use stylus. Most people who I know used stylus in few very specific applications and they just use finger for most tasks but to be fair you had to be very precise.
