It is still a little disappointing to see these new features not available to those us still running Exchange 2003 and Exchange 2007. I woudl think Microsoft would be wanting to push the Windows Mobile platform?
In my environment this would be one more way to show that our investment in MS tech is a good idea. I am constantly having to answer why the Iphone, Android, Blackberry should not replace the Windows Mobile phones. People bring in their personal devices, IPhones mainly and show off what they see as e-mail goodness. Many mid-level managers are attracted to these things.
Having new features that can be added to existing technology investments really goes a long way to forstalling these pressures. Telling management we need upgrade again (we just moved to Exchange 2007 last year) just to get these new features is not going to win me any fans.
