Information design guru Edward Tufte has posted his analysis of the iPhone’s user interface, which includes this video which you simply must see. If that video doesn’t make you want to run out and
venerate buy an iPhone, there’s something wrong with you.
He’s generally very positive about the UI, although he points out some “cartoony” elements here and there (really thick buttons, wasted space in the Weather app, etc.) that I don’t think I would have ever been bothered by until I heard what he had to say.
Some interesting comments in the article about the Weather app, too. I get the feeling there are tons of developers out there (some of whom are likely among the commenters) raring to go once the iPhone opens up to third party apps.
