Though he also makes a very good point that even Steve Schiller mentioned in the keynote (from what I've read, I haven't watched it). They kept the headphone jack because a huge amount of time is spent with the computer at a desktop plugged in to stereo speakers. Do you work at your desk using your laptop keyboard? So, if the majority of time is spent using an external keyboard, did apple create an external keyboard with the touch functionality? Will developers built their apps to take advantage of this functionality if it is only available to the subset of users who have purchased this new device AND are currently not at their desk??
