I think I like it better with Elon, than if there was some random sales pitch person with a perfectly rehearsed and forcefully over-enthusiastic presentation. It's a combination of respect for the man, and a sense in which we're geeking out over the features together in an informal and relaxed manner. Something like that.

There a happy middle ground.

People like Schiller or Federighi from Apple are both slick presenters, sometimes teetering on the edge of cheesiness, but it's all saved by the fact that you can tell they really know and care about the product.
