I had assumed this "rumor" of Salesforce.com switching 4,000 employees to Macs had in fact occurred several months ago based on following Simon's contributions to the Mac world and attending Dreamforce demos.

I'm not far behind making the switch myself. I've decided rather than running Parallels to maintain a stable Windows XP/Visual Studio machine and a separate Mac/Eclipse environment for general browser-based productivity and Salesforce specific work.

No surprise which one will get used the most. I just love the instant boot of the Mac books.

The all SaaS environment utilized by our company makes employee on-boarding, collaboration, and roaming much easier. It's vexing to see companies with only 12 employees shackled to Exchange. If migration is the only barrier to SaaS, then expect to see more service-oriented integration tools and vendors emerge.

Mobile productivity and multiple device synchronization is the next challenge. Google Phone had better be just around the corner.
