The best feature is the fact that for certain mobiles you can control your corporate profiles versus your personal profiles. That is amazingly important. Apple just supported the separation of corporate and personal profiles, whereas Android has been doing that for quite some time... Because Android supports that, if an Android phone is lost or stolen, I can wipe out all the corporate-related information from that phone and not touch the personal side. I can separate the apps and I can separate the ability to cut and paste between apps.
