As is annual tradition, a team of analysts from Piper Jaffray camped out at the Apple Store in the Mall of America on Black Friday. This year, for the first time, the group did the same at a neighboring Microsoft store. The results showed 47 percent less foot traffic at the Microsoft store than at Apple’s. Also, shoppers bought 17.2 items per hour at the Apple Store, compared to only 3.5 items per hour at the Microsoft Store, with all but two Microsoft  purchases being X-Box games. Most tellingly of all, while Apple sold 11 iPads per hour, during the observation period, Microsoft didn’t sell a single unit of its new Surface tablet. Uh oh! [Source Fortune]
