Good point; I missed that he was talking specifically about their managed email service vs. their hosting accounts. In terms of confidentiality, the Google Apps for Business terms and conditions are more reasonable than the free version. So, if he's open to paying a couple bucks, it seems like he could have just upgraded and saved the hassle of switching. Looking at the Rackspace offering, I realized that one big item (for me, at least) missing from the comparison is push support for mobile devices. Unless I'm misunderstanding, the Rackspace hosting requires that you purchase the 5x more expensive Exchange hosting in order to get push email support.
