This talk felt pertinent, and in line with a major theme that emerged at Interaction10, of respecting our humanity.
I thought I'd bring this to the attention of the group, in case you haven't already seen it. Apple has published an iPhone Human Interface Guidelines document. You can see it here: http://developer.apple.com/documentation/iPhone/Conceptual/iPhoneHIG/
I only skimmed through it, but I didn't see too much that was groundbreaking.
