During Black Friday, Minneapolis-area Apple Stores sold almost five times as many products as a Microsoft Store in the city, according to observations conducted by Piper Jaffray. Analyst Gene Munster comments that his firm spent about eight hours watching the Apple Stores, and found that traffic was up 31 percent year-over-year. An average of 17.2 items was bought per hour; at a Microsoft store, by contrast, the rate was only 3.5 items per hour. All but two purchases were Xbox games, and none of them were of Microsoft's Surface tablet.
