More technically-educated users represent a win for any company, Weider says.

"Part of my job as a CIO is to increase the technical savvy of our workforce, and Mac users seem to want to learn about technology more than Windows users," he says.

Many of his workers use Macs at home, so Weider was able to convince other executives that the healthcare companies needed to support those Macs and allow remote access to specific applications through Citrix.

"There is a real culture around the Mac," he says. "People that are Mac users talk to other Mac users, and really learn about their Macs."

5. The Cool Factor

Finally, Macs are just cool technology, Weider says. The aluminum cases and slick desktop interface make a statement.

"They are beautiful pieces of machinery," he says. "I went into a company that runs all Macintoshes, and it was awesomely beautiful."

For the majority of companies, however, information technology is a means to an end, and it's the destination that matters.

"In the end, the OS is like a car," Weider says. "Some are cooler than others—XP is a Chevy Impala and a Mac is an Audi—but, as a CIO, I am more worried about where we are going than the car we are driving."
