Google adds Android enterprise features to Google Apps
First of all, the enterprise upgrade will add lost device location. The administrator can then change the device's PIN and password remotely. Secondly, the admin will be able to remotely encrypt the device, should there be a sudden impending security concern.
And thirdly, users will be able to search the Google Apps administrator's directory, and use those contacts just like they were saved on their own device.
