For the past decade, the only Operating System choices for enterprise mobile applications were Windows Mobile and Windows CE. Today the OS landscape has changed drastically, Android and IOS are beginning to see usage in the enterprise.

These companies will need to start thinking about moving their applications to a new platform.
