Collingwood wrote a lengthy user policy manual for the iPad that answered most of those questions. He decided to allow for personal use on iPads because, in truth, he wouldn't be able to stop it anyway.

Fact is, iPad owners want to share their work-related iPads with family and friends, use the same app to manage personal and business travel itineraries and calendars, and even use a familiar app to find a restaurant for both entertaining clients and taking out spouses. The iPad has blurred the line between work life and personal life.

Then there's the nuts and bolts of managing and securing enterprise iPads. CIOs wanting to jump on the iPad bandwagon have to research and choose from software vendors barely out of the startup stage. For mobile management iPad tools, Collingwood chose three-year-old MobileIron.

MobileIron's strength is its ease of use for iPad owners, says CIO Ashin Ballal at KLA-Tencor, a Silicon Valley semiconductor equipment maker posting $1.8 billion in annual revenues. Last summer, KLA-Tencor rewarded all , and Ballal was tasked with supporting them.
