Cult of Mac author Leander Kahney found that Steve Jobs hasn't cut a single check to charity. Maybe he puts his family first, right? Well, no. For those of you who haven't read the roman clef A Regular Guy (by Jobs' biological sister), we'll connect the dots: it turns out the mogul refused to pay child support for his daughter Lisa, denying she was even his, for years. Can't imagine that's healthy. At least he named a computer after her — okay, a failed one, but there's only so much love a dad can give, eh?
