A chart and map posted on Tuesday on Net Application's Market Share site shows that there are more Mac users than average in "blue" states such as California, New York, Oregon and Vermont, and fewer in "red" states such as Mississippi and South Carolina.
One of the first things we did with our latest upgrade was to get a view of Apple's market share by measuring the usage share of all Macintosh operating systems. This map jumped out at us as having a striking resemblance to the U.S. red/blue election map from 2004:
Of course, this isn't chart doesn't show that the Mac is the dominant platform, just that in these states there are more Mac browsers counted than the 6.8 percent average. And some states appear to defy the trend, such as New Mexico and Utah.
I note that Washington is leaning to the Mac despite the obvious pull of Redmond. Amazing. Go switchers.
