– Piper Jaffray analyst Gene Munster said that Apple retail stores are having a very hard time keeping up with demand for the new Mac mini and iPod shuffle. In a survey of all 98 U.S. Apple Stores, Munster said he found “virtually no supply” of the new products, with only three Mac mini units and zero iPod shuffles. “We believe initial demand for the Mac mini and the iPod shuffle has exceeded what Apple had been expecting,” the analyst said in a research note to clients Monday. Munster reported that the average waiting list per store for the Mac mini was 18 people, while the average wait for the iPod shuffle per store was 120 customers.
