Earlier today, Glenn Fleishman took photos of the crowds outside the Seattle Apple Store.
It looks like there were at least a hundred people or more lined up (the line eventually snaked stretched to 25th av):

By the time I drove by at 8:30pm, the line was gone. A few people were milling about in front, and the Apple employees were lined up inside the door waiting for customers, so I’m guessing there were still phones in stock.
