Google is now taking aim at Research in Motion and Microsoft for a piece of the enterprise smart phone market. It’s going to be tough sale to convince Blackberry users to switch to an Android phone but with release of Android 1.5 OS and now Microsoft Exhange support it should be a little easier.

The next hurdle for google will be improving and adding more security features.
