Agreed. And not only is he on camera in front of thousands of people (one of them being Steve Jobs), he's also got a cable coming out of the dock connector going to the giant screen; if he unplugs it, it'd be a real interruption and distraction to the presentation. And, (especially on a not-yet-final product like the iPad) you'd worry about whether the external display would connect back up if you replugged it, etc... I guess what I'm saying is that I sit way differently when my laptop's hooked up to, say, an external hard drive and I don't want to accidentally pull out the USB than when I'm curled up on the couch with a blanket and my worry-free not-attached-to-anything phone.
