Windows Mobile 6.5 has been discussed for some time, but today at the Mobile World Congress 2009 Microsoft officially annouced it.  As with most Windows Mobile updates, they are focused on the consumer (phone) market, so it remains to be seen whether there are any improvements that will help Data Collection devices.  It does seem that Microsoft is trying to make the touchscreen operation more finger-friendly, but we'll see if this is a general improvement or just within certain applications.
