Just got back from a ATT retail store in NYC. Got there at 6 am, there were only 2 other people waiting. By the time the store opened at 7 am there was max 15 people in line, 10 of which had pre-ordered. ATT I guess changed the whole 2 line policy because they were letting pre order customers go in first but I waiting about 15 minutes until I was able to get in and grab my new 32GB black 3G S. Playing around with it now, the screen seems a lot nicer and it's definitely snappier. Would be interested in hearing how other people fared with ATT walk-ins.
