Sales of Apple desktop computers fell 38 percent in November, according to retail research firm NPD.The figure compares to a 15 percent drop in U.S. sales of Windows desktop PCs and a 20 percent domestic cut for overall desktop sales during the past month.

Mac U.S. sales were flat in November, falling 1 percent as PC sales grew 2 percent, according to NPD. The numbers appear to reflect a consumer spending tightening and Apple’s reluctance to shift from premium prices.

While PC makers, such as HP and Dell, cut holiday prices by up to 50 percent, Apple introduced 5 percent to 10 percent discounts since December of 2007, Piper Jaffray analyst Gene Munster told the Wall Street Journal Tuesday.
