I'd also like to add my 2 cents.
Support for downloading GPS units to ArcMap is sorely missing at this time, simple products can seemingly easily download and upload tracks and points to and from GPS units. The core comms agent must be there somewhere as you can connect a real time GPS now to ArcMap, but not download tracks or waypoints.
This is core functionality that is missing from such a robust product such as ArcMap. Heck even the FREE Explorer can import GPX files natively while the expensive and robust ArcMAP simply can't.
I feel that ALL public safety departments and teams would give ESRI a huge round of applause if they would add support to pull data directly from GPS units. A bigger round if we had the ability to push polygons and points to the GPS also.
Thanks
