Not just on their Ipods either. You also get a goofy cable on their macbooks and on the shuffle headphones. And now they cut the firewire from the macbook line (I think the mackbook pro still has it). One hand gives and the other takes.
The white ones always had Firewire 400 too (http://www.apple.com/macbook/specs.html). There was a brief period when the 15 inch Macbook (later renamed Pro) had no Firewire.
The Air, predictably, doesn't have Firewire. It barely has USB...
