Funny, whenever I run into an annoyance on the iPhone, a little whiny voice in my head inevitably says, "Aw, but I can do that so easily on my Newton!". So, as a Newton fan, I can't help but think that the iPhone is still only the verge of 'shifting the paradigm' - what it lacks, as Jose says, is a real input method, and some of those Newton OS touches that made it feel like all your data and applications were seamlessly interconnected (if that makes any sense - I'm thinking of, eg., tapping Assist). At the moment, because all my work involves writing at length, I have to carry the iPhone and an Eee PC, or, when I don't want/need to be online, the good old MP2100 plus keyboard. Fingers crossed all the chatter about the "brick" project being a big iPhone/small tablet device turns out to be true.
