Earlier quoted context omitted.
Docomo phones were(are?) a Japan-only irrelevance. Granted - Symbian was a thing back then, but can you buy a Symbian phone today? Consumers voted with their money, and they wanted iPhones, not Nokias. Fast forward to 2019, Nokia is nothing more than a trademark - making generic Android phones on one hand, and cashing in on nostalgia with their feature phones on the other hand.
That doesn't change the fact that Apple did NOT create the smartphone.
They created THE smartphone - the definitive item.
