I'm a very experienced scanner user, and can see myself getting one. I don't travel much, but it would be extremely handy as a "road trip" scanner for anyone, including experienced users, that don't want to look up and prorgram every county along a days long trip. Imagine it hooked to GPS and automatically tuning to the type of scanning you want to do. The record/play back feature is very cool, and I hope that makes it over to the XT lineup soon. I often get asked what scanner to buy, from people who have no clue or interest in figuring out a traditional scanner. This will be an easy answer. Buy it, choose your location(s), choose what you want to listen to, and go. I listened to the Grand Prairie, TX P25 system briefly, but not enough to get a good comparison.
Someone mentioned that the RadioReference database will really need to be kept up todate or would require a lot of work, especially in regards to GPS coordinates. That is true, but much have that has already been done, and been in the works for some time now. For many of us, part of what we enjoy most about the hobby is figuring out and sharing scanning information. As I watched the screen on the demo unit, I thought, hey I helped define/describe that system or channel on RadioReference. That's cool to be a part of what even more people will enjoy now.
Happy Scanning,
Ben
