Looks like people enjoy technology that works properly:

Apple is moving up the charts, toppling Acer to become the third largest PC vendor in the U.S., according to a survey from Gartner.

Apple defied a weakening economy to record a 38.1 percent growth rate in U.S. PC shipments, according to Gartner. Overall PC shipments in the U.S. grew just 4.2 percent to 16.5 million units during the quarter.

Right now, Apple is firing on all cylinders. The Mac, the iPod, the iPhone - and they all work together well. Now ponder the equivalents for Windows. Individually, there are some nice products, but collectively, they just don't "fit" as well as all of the Apple stuff.
