I was in an Apple Store the other day to pick up an iPhone belt clip, and I was totally flabbergasted by the sheer number of people in there. It was insane--there were people trying things out, two older women on folding chairs sitting at the feet of a store employee taking a class on something or other, and scads of people buying everything in sight. Most people weren't in line at a cash register waiting to buy their purchases, they were buying and paying for their merchandise at any spot in the store via handheld point-of-sale PDAs that most of the employees were toting.
It really was an unbelievable experience to see so much buzz around Apple products--and to think that some folks swore that the stores wouldn't work back when they were first announced.
I'd say they're working pretty damned well.
