I headed over to Best Buy first thing Friday morning… they opened at 8AM and handled the iPad Air rollout very nicely. It was raining hard… they gave reservations for particular units to people who were there early and didn’t make anyone stand in the rain. (They also handled the iPhone 5 very nicely, even making appointments for people to come in to activate their new phones – not as streamlined as pickup at Apple but still pretty civilized).
I don’t think there were more than 10 people there at 8AM. I was in and out within a few minutes. I went home, backed up my old iPad to iTunes, connected the new iPad and restored. The whole process was very painless (hint: to help keep it painless, choose the option to encrypt your backup – otherwise iTunes will intentionally not store passwords and authentication information in the backup).
