steve jobs has failed massively before and it never stopped him. when john carmack's Daikatana failed, he had over 20 years of experience in the game industry -- people like them don't stop because one of the many, many things they've worked on in their long careers don't pan out precisely they way they would have liked. thank god for people like that.
i'm certainly going to wait at least a few months to get an iphone, though.
also, i'm skeptical of people who put raw ascii characters like "~ ~ ~" instead of using an HR element. this is HTML, people, use what's available. scoble does it too and i always mentally discount punditry bullshit from people who don't understand the medium they make predictions about.
