"So, your kids must love the iPad?" he asked. But Jobs replied: "They haven't used it. We limit how much technology our kids use at home."
Bilton said he responded "with a gasp and dumbfounded silence".
"I had imagined the Jobs' household was like a nerd's paradise: that the walls were giant touch screens, and the dining table was made from tiles of iPads," he wrote.
Walter Isaacson, the author of the biography called simply Steve Jobs, told him later that "every evening Steve made a point of having dinner at the big long table in their kitchen, discussing books and history and a variety of things".
"No one ever pulled out an iPad or computer. The kids did not seem addicted at all to devices," he added.
Chris Anderson, ex-editor of technology magazine Wired, who has five children aged 6 to 17, agreed with the Jobs family approach.
"My kids accuse me and my wife of being fascists and overly concerned about tech, and they say that none of their friends have the same rules," he told Bilton. "That's because we have seen the dangers of technology first-hand. I don't want to see that happen to my kids."
There is some scientific support for the idea that modern technology can be damaging. A study, published last month, of 11- and 12-year-olds found that removing digital devices, including televisions, for five days saw an improvement in social skills.
