do they replace it with the same exact model you had before? I mean, if you had the old 15" Unibody design without the SD memory card, and something was wrong with it and they were going to replace it, would they replace it with the same model or just give you an upgrade to the SD card one? I mean, they don't make the old ones anymore, right? I guess they could have them in supply still maybe though. This isn't a personal question, I'm just curious about it.
