For a moment he teared up. He talked about his other girlfriends, particularly Tina Redse, but said he ended up in the right place.
He also reflected on how selfish and demanding he could be.
"Laurene had to deal with that, and also with me being sick," he said. "I know that living with me is not a bowl of cherries."
Among his selfish traits was that he tended not to remember anniversaries or birthdays. But in this case, he decided to plan a surprise.
They had gotten married at the Ahwahnee Hotel in Yosemite, and he decided to take Powell back there on their anniversary.
But when Jobs called, the place was fully booked.
So he had the hotel approach the people who had reserved the suite where he and Powell had stayed and ask if they would relinquish it.
"I offered to pay for another weekend," Jobs recalled, "and the man was very nice and said, 'Twenty years, please take it, it's yours.'"
He found the photographs of the wedding, taken by a friend, and had large prints made on thick paper boards and placed in an elegant box.
Scrolling through his iPhone, he found the note that he had composed to be included in the box and read it aloud:
We didn't know much about each other twenty years ago. We were guided by our intuition; you swept me off my feet.
It was snowing when we got married at the Ahwahnee.
Years passed, kids came, good times, hard times, but never bad times. Our love and respect has endured and grown.
We've been through so much together and here we are right back where we started 20 years ago -- older, wiser -- with wrinkles on our faces and hearts.
We now know many of life's joys, sufferings, secrets and wonders and we're still here together.
My feet have never returned to the ground. By the end of the recitation he was crying uncontrollably.
When he composed himself, he noted that he had also made a set of the pictures for each of his kids.
"I thought they might like to see that I was young once."
