I also think the phone OS will become a problem when used in a business network. At least as they are right now.
A simple example, is there an app that secretly monitors your USB ports and detects when an unauthorized device or flash drive is connected and sends an email to your boss? I know that sounds extreme, but we have that where I work.



...Don't worry, as part of the core development team, I am exempt from those rules. But as a core dev, a smart phone would never have the power needed for me, so that's a non issue.
