Interesting, but ultimately a load of nonsense.
I say bull. Nokia did not have it all nailed. HTC on the other hand, had it nailed (sort of)and launched lots of touch screen devices. Ericsson also had several. Yet, it's all bull because the iPhone had something that no one else had, a intuitive UI and a intuitive store (music initially, but apps to follow). That locked down system was what made the big difference. Nokia was never even close to launching an ecosystem, and neither was anyone else, except perhaps Palm who had something close to it, but not a centralized point.

That's Nokia. They made good phones, but when the OS and services outgrew what could be made using simple systems like S40, they couldn't handle it. That's the mistake they made, they didn't hire in top programmers and software architects that could make a unified Nokia ecosystem.
