Google has released version 6.0 of the Maps application for Android, bringing with it the ability to view inside certain locations in the US such as airports and shopping centres.

Detailed floor plans automatically appear when you’re viewing the map and zoomed in on a building where indoor map data is available. The familiar “blue dot” icon indicates your location within several metres, and when you move up or down a level in a building with multiple floors, the interface will automatically update to display which floor you’re on. All this is achieved by using an approach similar to that of ‘My Location’ for outdoor spaces, but fine tuned for indoors.

With the release of the Android 4.0 SDK it is possible to play with Google's support for Exchange ActiveSync which is included with the Android SDK emulator package.
It is important to note that just because the build of Android supports it, it is down to individual device manufacturers as to whether they choose to implement Exchange support, or they may choose to develop their own, superior, Exchange email client software.
