Go back and watch the iPhone introduction keynote.
There it was - literally, Steve's happiest moment. Doing what he loves to do. With a great device, leaps and bounds ahead of the competition at the time. Audible gasps were coming out from the crowd. Everyone hanging from his. Every. Word. The audience applauding every couple minutes. He was truly, profoundly happy.
He's lived his dream man. He's already done it. If only we could be so lucky.
He's not gonna reveal hover boards or time travel. No holograms. There's not gonna be another sock-knocking product like the iPhone for a while. Better iPhones every year, yes. Life-changing devices every year, no. And certainly not from Steve, considering he's got another year or two left in the game. Tops.
If Steve had a failing, it's that he's too convincing. Kids believe in magic now.
