For many a business user, the thing that has kept them from considering the Android platform is the lack of solid, and complete, Exchange support.  One of the early Exchange client makers for Android, NitroDesk, has just announced that it has released the production version of its push-capable Exchange client to the Android Market.

In addition to the push support for contacts, appointments, and email, the new version of TouchDown also supports PIN code security and support for a remotely initiated wipe of the device – in case it gets lost or stolen.

People interested in the app can download the application, which includes a 5-day full trial, from the Android Market, where it is called “Exchange By TouchDown”.  After the 5 days are over, the app continues to work in a read-only mode.  A second application called “TouchDown Pro License”, which retails for US$29.99, can be purchased and installed to activate the full functionality in the Exchange By TouchDown client.
