Was it just my imagination or did a couple of the guys presenting yesterday look and sound really nervous .couple of them fluffed a few lines esp the guy who showed the iPads and MBPs. Even Tim Cook started off a bit shaky and later I could see his coach or someone told him to speak a little slower. The only guys who presented effortlessly were the software (mavericks guy) and the apps guy. Sorry I don't remember their names. I only bring this up because among other things Steve Jobs was a pretty flawless presenter.
