Well, hey, couple years late to respond to this, but oh well.
I have worked extensively w/New World since 1999, when we went with their platforms for our CAD/RMS/JAIL and Court..quite an extensive list. I'm not saying getting the system up and running was carefree (which system is???) but this product has a lot to offer both in dispatch and mobile units.
The nice thing, when a new client comes on board and pays for features to be implemented, all users get the new features in the next upgrade.
Lots of information at dispatchers fingertips and a fairly easy system to use..as long as you pay for maintenance, you will be getting newer versions regularly.
Only con I can think of: the upgrades tend to set us back a bit and we had to work out the bugs...but I think that goes w/any system out there.
Good customer service as well.
I have since switched comm centers, in the new place I am working we are getting a new cad. If it wasnt almost a done deal, I would really advocate for New World.
