We headed out at 6:30 AM to the Apple Store at Willow Bend Mall in Plano, Texas. If I had to guess, I'd say that when we arrived shortly after 7:00 AM, we had about 500-600 people in line in front of us. I've attached a rude sketch of the line that shows where we started on the other end of the mall, wound around the play area into a zig zag queue, before making it to another line in front of the store. We entered Apple around 3:30 PM and breezed through getting the whole family new iPhones in less than 15 minutes.
Eight or so hours in a line was made bearable by the folks at Apple providing food and drinks from mall vendors. We had Chic-fil-A, Auntie Anne's, Krispy Kreme, Hagen-Daz, and California Pizza Kitchen. A big thanks to the staff of Apple Willow Bend for making a long wait tolerable.
Oh, and the new iPhone rocks.
