Remember that piece of news saying IBM was expanding its Mac Pilot Program? It sure looks like more companies are drawn into what the Mac can offer, at least from a security point of view. Salesforce plans to employ 4,000 Macs for its entire staff, a piece on 9to5mac reveals, making it one of the largest enterprise software companies to use Macs.

"The opportunity to use the innovative iPhone OS platform to deliver compelling Software-as-a-Service applications to mobile users is empowering to us, and ultimately, our customers," said Marc Benioff, chairman and CEO of Salesforce. "They are asking us for new ways to harness the power of Force.com to access their business information on any device regardless of location."

You must be wondering why. Why would Salesforce all of the sudden want to switch to Mac? Surely, Mac fanatics already have the answer to this question, but indulge us by reading iPhone developer Alex Curylo's blog entry, highlighted by the aforementioned source: "Why, you ask, Security! The resources it takes to defend against all the stuff the baddies throw at a PC, it's just cheaper/easier to pay a few bucks more for a Mac and not have any of those issues."
