If you're having trouble finding a Wii, you might have a relatively easy time getting on at the Nintendo World Store in Rockefeller Center, on 48th Street between 5th and 6th Avenues. They claim to have new stock every day, and I recently saw some for sale at 5:45 p.m. on a weekday. The last time I'd checked, a few months earlier, they were selling out within a few hours of opening each morning.
