According to a post on Alex Curylo's Under The Bridge blog, Salesforce.com may become one of the largest switchers of all time. Curylo's source tells him that 4,000+ staff will be issued Macs when their leases expire:
Salesforce.com is giving Macs to all employees. Yup, all 4000 of us; we are going to be one of the largest enterprise software Mac shops around. As the leases come up for the Dells, IT is replacing with Macs.
And 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.
With the Google Apps integration, and moving to the Mac, we will be free of the clutches of the Redmond Beast!
One commenter says "I find this tough to believe considering how SF integrates so tightly with Outlook." Another notes that "They did participate in the iPhone demo w/Jobs, didn’t they?" (Thanks MacDailyNews).
