The very first iPhone to me was the most ground breaking...back in 2007 when smart phones were not smart and primarily phones more than anything else. It brought to the table the intuitive and user friendly touch screen, the form factor, the introduction to "apps", the remarkably improved camera functionality, true web browsing, a digital keyboard that could be customized for whatever language you preferred...etc etc etc.
I mean the first iPhone didn't invent most of these things, but it damn sure put it in the consumers hands in a way where they really learned how to use it, and change their lives based on the functionality.
Ever since, they've improved on it...sometimes slightly, sometimes ENORMOUSLY...but all the while, still improvements and not reinvention. To me, if you talk about breaking ground, you reflect the beginning, and as much improvement as has been done to each and every iPhone (and really every smart phone out there) since 2007, the genesis factor was still the very first one...which by todays standards is just an awful experience that no one would prefer, but in 2007...it was jaw dropping.
You clearly never owned anything other than a Nokia 6210 until your iphone. All the the things you mention existed, and some in better form, before iPhone was released.
