"While they are much less secure, you can't put a blanket statement on it because companies have different security requirements," Schadler says.

More than security, the strain iPads will put on wireless networks has everyone concerned. There's simply not enough mobile broadband bandwidth available. While moving from 3G to 4G will help, Schadler says, "It won't take many FaceTime video chats for the thing to drag down to a halt."

On the 3G side, this means a company might not be able to deliver mission-critical iPad apps to mobile workers when they need them.

On the WiFi side, companies will have to ramp up their capacity. It's already expensive to provide WiFi access points for all the employees that want to wirelessly connect to the network on their laptops.
