You can buy an iPhone at Best Buy, but more likely you won't buy anything at all this Xmas. The company's revised forecast predicts revenue between now and February may drop by 15 percent. CEO Brad Anderson's official statement is blunt: "Since mid-September, rapid, seismic changes in consumer behavior have created the most difficult climate we've ever seen ... Best Buy simply can't adjust fast enough to maintain our earnings momentum for this year." Cool, but seismic changes? Brad, come on out from Minnesota and we'll demo a real earthquake for you.
