A Piper Jaffray Cos. research team counted heads for eight hours Black Friday at Apple Inc. and Microsoft Corp. stores in the Mall of America near Minneapolis, CNNMoney reported. The stores are across a hall from each other. Here’s what the head counters came up with:

• There was 47 percent less foot traffic at the Microsoft outlet than the Apple store.
• Shoppers bought 17.2 items per hour at the Apple store and 3.5 items per hour at the Microsoft store. All but two of the Microsoft purchases were X-Box games.
• Shoppers at the Apple Store bought an average of 11 iPads per hour. Despite heavy television, print and billboard advertising for the new Microsoft Surface tablet, not one was sold during the two hours Piper Jaffray spent monitoring that store.

Meanwhile at the Apple store, traffic was up but sales of Macs and iPads were down from last year, possibly due to supply problems, the researchers said.
