I hope I'm posting this in the right spot... It concerns the new iMac, so I guess this is right... Anyway, I'm one of the hundreds of people on here anxiously anticipating the possible (and highly plausible) launch of an improved iMac next January. Now, I don't really want a whole other debate on what the update will be, how much it will cost, whether blue tooth can penetrate aluminum, ect. What I'm wondering is how does this macworld thing work? All I know is that SJobs will give hid keynote which introduces the new products, but when does this happen? Is it at the beginning or the end? Also, when he announces them do they appear in stores the next day, or does it take a week or two. How has this worked in the past?
