I really miss, as a late 90's/early 2000's apple fan, seeing Steve come up and joke with the audience then just show off real products or features and why they're cool. They really sterilized this whole thing after he passed. It's as exciting as a Microsoft keynote now.
Just watch a normal presentation like Mac OS X 10.2 or 10.3, it's not iPhone level earth shattering but he made it fun.
Also—and this sounds like a small thing but it's really not—when Steve said something like "we have some really exciting updates for you today," he really truly believed it. I just went back and re-watched his appearances on WSJ D1, D2 and D3, and he was actually psyched about every little iTunes update.
It's not just Apple, Microsoft but whole corporate world, and hell - even open source projects use same sterilized safe language of "we're so excited" in communication with users, customers. That's the actual reality distortion field.
He never let a little smoke distract from a good iRack demo.
I want to celebrate your comment, and the energy around it, and I'm excited for the next generation of replies to build on this momentum.
I remember one where there were technical issues so Steve just started telling stories about the old days with Woz... impossible to imagine that from ANY tech company today
