The first category is platform-level devices that are allowed to access the highest number of apps plus more types of corporate data and thus receive the most support. "iOS and Blackberry devices (http://www.blackberry.com) might belong to this category as they are more mature," said Chuang. "Companies should also recommend employees to pick these devices."

The second category is appliance-level devices, according to Chuang. "Users of these devices are allowed to access fewer apps such as e-mail and calendars," he said.

The last category is concierge-level devices--machines that run nascent OSs and might not be used by many employees. "IT must give some level of support to these devices and at the same time track closely their support costs," said Chuang. "Who knows? These devices might be popular in the future. One example is the iPad--despite its prevalent use today, it was a concierge-level device a few years ago and people were skeptical."

"By knowing what devices your employees are using, you will have an easier time planning and building your apps and apps usage policies."
