"Here's how far I am willing to go: I believe the iPhone will ultimately be judged a more important product than the original Apple Macintosh."

I've been saying the same thing for a while. Like many revolutionary products the iPhone isn't the first device to ever offer these features but it IS the first device to make them accessible to the masses. Part of that is a good user interface but an equally, or possibly more, important part of it is advertising. Apple educated customers on what the device could do out of the box. Now they're even advertising third party apps. As a result many people are able to use services & technologies that were out of reach to them before -- or they were ignorant these things even existed. Lots of people will say marketing doesn't matter and it's just fluff and blah blah but making people aware of something, and making it possible for them to use it, is a huge part of what makes a technology revolutionary.
