Please excuse my ignorance. I'm not very Apple educated.
Lets say Jobs anounces on October 7th that "Hey we got a new super cool iPod" how long before they would be available? Would it be magiclly that day that all the retailers have them behind the counter ready to sell, or is it like Apple has them all made, boxed and ready to ship or....something else?
I know every situation is different but aproximitly how is it done?
