Here's some very interesting info from eWeek for you to share with your boss. They've created a slideshow outlining the security risks that companies subject themselves to when they let employees use portable devices like Smart Phones, WiFi, unprotected laptops, etc.
Key point to make when you share this: ZENworks Endpoint Security is designed specifically to address these risks.
Excerpt from eWeek:
"Employees can pose security threats to your enterprise IT infrastructure through mobile devices such as smart phones and laptops, as well as the various networks and applications with which their unsecured devices are liable to interact. Enterprise IT administrators, network administrators, and enterprise security workers and consultants should be aware of these security risks."
