Did anyone of you go to the Surface Challenge? How was the turn out? I went to the one here in Scottsdale Arizona and the turn out was mediocre. I was first told they would have a vary limited number of Pro 2's but can't disclose which ones or how many. I wanted the 256 but they said they have none of those. 4 people walked away after hearing that but I stayed for the Challenge because they were giving out MS Gift Cards. Anyway, they had 2 lines, one for the Challenge and the other for people who just wanted it buy. I decided to skip the Challenge and wait in line to buy. After after about 30 min of lame trivia games, like "what is your name? you win a hat..." An MS employee comes out and asks us which model we wanted. I told him I wanted the 256 and he just said "OK". I told him I was told they don't have any but he said they had enough for the turn out. I was so glad I stayed and felt bad for the 4 others that took off earlier. I think there were only about 30 of us in line and half already had pre-orders. Pretty sad for a launch. They started handed out the prizes (shirts, hats, pens with stylus tip, flash lights) to everyone at the end because they had so many left over. They also had sacked lunches and when I left, they still have more than half left over so people were taking a multiple bags of those too.
