The cover story on last week’s Business Week was about the Mac’s growing presence in the corporate world.

While this trend is not particularly surprising to most seasoned Mac users, it’s notable for the fact that Apple has spent very little resources directly targeting this market. And yet, March, 2008 sales for Macs exceeded all forecasts, climbing 51% over the previous year. The article points out that combined Mac, iPhone and iPod sales grew from $5.2 billion in fiscal 2002 to $24 billion in 2007. Apple’s share price has risen 2,300% over the past 5 years.

It appears that a number of factors are at work here, including cross over from iPod and iPhone sales. However, one major factor may be the troubled Vista operating system, which seems to have been a dog from the start. Microsoft’s own Steve Ballmer calls Vista a “work in progress.”
