The only people "lining up" on release day will be the 200 or so people on this macbook pro thread, but since we are spread out across the country, the biggest line will be 5 or 6 people. The general people don't care about i5 or i7, they just want a mac to look cool in front of their friends or at starbucks, they wouldn't care if we stuck a pentium 4 processor in there! They just flat out do not care. It isn't a new product like the iPad, it is a simple processor* update.
*A regular person will say "processor, like the food processing plants right?"
