Meh. Just because she had some success at selling rain boots and umbrellas doesn't mean she'll make it here. I thought she seemed amateurish in the video. As a former CEO, she should have had plenty of experience speaking in public--and this wasn't even in public, it was in front of a camera--to be good at it. And that jerky, fake use of the hands to keep from seeming nervous, PUH-LEEE-SE.
I'm not holding her to some impossibly high public-speaking comparison to Jobs, I just expect that she can hold her own on stage and be able to articulate a clear message in a camera-friendly way. As opposed to: using "Um" every other sentence, flapping her hands everywhere, eyes swiveling around in their sockets, clearly wanting to be anywhere but in front of that camera.
