I use function keys a lot for programming, but there's plenty of apps I don't need them for. Having context aware buttons sounds like a nice step, especially if it has the ability to securely store and use my credit card for purchases. How about going boldly into the future rather than being tied down to something which doesn't get a ton of use in most situations! *Edit: of course my reply doesn't have anything to do with the headphone jack. For simplicity and space removing the jack made sense, but for ease of use and standards there's good arguments for keeping the it around. I argue this case is different because it's not widely used and it's prior use (fn keys) can be duped by the magic bar.
