So there's a pretty lengthy thread I made a few days ago about a BTO 17" I bought recently that had display issues and needed to be sent back as an RMA. The rep said he would replace my unit with the same model(BTO with 7200RPM drive), but I was thinking about just getting the stock 5400 drive instead. To my understanding, the ONLY real advantage to buying a stock model versus a BTO/CTO model is the ability to go into any Apple store to get a replacement if necessary(right?). I was unable to get a replacement for mine since it was a BTO and they do not stock any of the BTO units. Anyway, my question is, wouldn't this advantage technically only last for as long as the stock models are on shelves? As in, once Apple refreshes the current lineup, wouldn't all the people with stock models lose their ability to get it swapped out at the store, since they no longer have those models in stock, thereby requiring them to send their unit back to Apple by mail if a replacement is required? Sorry for the total confusion but I'm just wondering if there really is any advantage to getting a stock model other than being able to exchange it if you have any problems within the first (30?) days. If so, should I change the order for the replacement unit from a BTO 7200RPM to a stock 5400RPM?
