The wait time to play the Nintendo Wii at the E3 2006 was pushing 4 hours apparently yesterday. Compare that to a mere 30min. for the Sony PS3 - Nintendo is the winner of E3 2006 alone based on this fact.

Here is a video on Youtube (via digg) walking along the Wii line. The video takes over 2 minutes. The line just does not end. I do not know how the attendees have been able to put up with this gruesome wait time. After 3pm Nintendo had to stop people from getting in line, because they would never get to play before the show closes.
