Jobs responded, and the two engaged in an after-midnight e-mail debate over lockdown, Cocoa vs. Flash, battery life, and whether 'freedom from porn' is a bug or a feature. 'The times they are a changin',' quipped Jobs, 'and some traditional PC folks feel like their world is slipping away. It is.' Tate was unswayed by the Apple CEO's reality distortion field, but did come away impressed by Jobs' willingness to spar one-on-one over his beliefs — at two in the morning on a weekend."
