Apple's late co-founder Steve Jobs has had another book written about him, this time by ex-girlfriend and mother of his first child, Chrisann Brennan.

Jobs dated Brennan on and off for five years after meeting in 1972 when they were both studying at Homestead HS in California. They split up in 1977, but Brennan was already pregnant with Jobs' first child, his daughter Lisa.

Despite a paternity test that proved Jobs was Lisa's father in 1979, Jobs still denied that he was her father, telling Time magazine that "28 per cent of the male population in the United States could be the father" in 1983. He later accepted that Lisa was his daughter and went on to form a relationship with her.

So it's not particularly surprising that the book Brennan has written doesn't paint Steve Jobs in the best light. However, we can't help but think that Brennan's new book, or at least this first published excerpt, is fishing for headlines from the tabloids.

New York Post has shared an excerpt from the book, called "The Bite in the Apple: A Memoir of My Life With Steve Jobs", that gives an insight into Jobs' early life, though probably a rather biased one thanks to their troubled relationship. The article is a prime example of that headline fishing we mentioned: "Ex dishes on sex life with Steve Jobs".

Brennan was Jobs' girlfriend during an important period in Jobs' life, when Apple was just beginning to take off. However, according to Brennan, the growing success of Apple caused Jobs to change.

"As Apple grew, so did Steve's sense of self-entitlement," Brennan writes. "In parallel they both seemed to take on lives of their own."

"Steve had always been a brilliant misfit, but at this time – to be generous – he wasn't managing his growing power very well… Excellence had always been a gorgeous thing in Steve, but now he was using it like a weapon," she writes. "He'd look for excellence and when he didn't find it, he'd behave badly and take it out on people."

"Steve was uncontrollably critical. His reactions had a Tourette's quality – as if he couldn't stop himself."

While this may not be a nice quality for those close to Jobs, it's likely that some of his critical nature contributed to the success of Apple and its products.

We're not sure whether we'll be picking up Brennan's book when it goes on sale on 29 October, because, judging by the excerpt we've read, it seems like something of a rant (that she's perfectly entitled to) that probably doesn't give a real sense of the late Apple co-founder. Of course, before reading the entire book we can't say that that's all the book offers.

We'd recommend reading Walter Isaacon's official biography of Jobs instead, which still creates a picture of Jobs as a bully who got his girlfriend pregnant and denied the child was his, parked in handicapped spaces and screamed at people, but also that he was someone to be admired for many reasons.

Isaacson once explained: "[Jobs] could be totally charming when he wanted to be, but he was not relaxed. He was the most intense, emotional person, and I think that I found myself emotionally awed by him. Emotionally inspired by him."

When asked whether he liked Jobs, Isaacson said: "No, but I wouldn't have given up for a moment the chance to be in his presence."
