“Piper Jaffray’s Gene Munster spent the day after Thanksgiving as he has every year since 2008: Standing in an Apple retail store counting sales,” Philip Elmer-DeWitt reports for Fortune.

“In eight hours, he (or his team) watched iPads and Macs walk out the door at the rate of 14.8 and 10.1 per hour, respectively,” P.E.D. reports. “In a separate note, Deutsche Bank’s Chris Whitmore reports that the iPhone 4S was selling so briskly on Black Friday that about 75% of the Apple Store he called ran out of one model or another. Apple replenished supplies overnight and the next day only 30% of the stores reported iPhone 4S stock outs.”
