I found the upgrade to be extremely helpful. I view MPEGs with pocket TV and found significant differences between 2002 and 2003. Just as an example two videos played at 8 fps and 12 fps on 2002, Now those same 2 videos play at 13fps and 20fps. The internet explorer update is also extremely useful esp since I can now check my yahoo accounts without having to use an older version of internet explorer (all of you Pocket PC 2002 users who have wifi and yahoo email accounts know what I mean). These are just a couple of the enhancements I've discovered in my 3 days with Pocket PC 2003...
