My plan for 7/11
I'm going to leave work a little early (~3:30pm), and there's an AT&T store on my way to the subway, so I'll stop there first. If that looks promising I'll go there and get it. If they're really busy or out of stock then I'll hop on the subway, head to my car, then drive up to a nearby mall that has an Apple store and get in line there to wait however long it takes. (Assuming they haven't sold out.)
