I have pre-ordered in the past with the 4s and UPS showed up late afternoon around 5pm. My watch didn't arrive until 7:30pm. With my 5s I was forced to stand in line because there was no pre-order. The experience was actually pretty fun. I'm leaning toward doing the same this year. I'm going to a concert the evening of the 25th and prefer not to be at home waiting for UPS to show up or possibly missing delivery because I'll need to leave around 5pm for the rock show.
