Congratulations for creating a wonderful and friendly software! I'm looking forward to (and I think the people here too) put our hands on a new device that has Mapopolis software :-D
I got a nuvi 350 from my wife and seriously, I had to return it on the very first day. Once you get used to Mapopolis, it's hard to use nuvi (a "abcd" keyboard can drive anyone crazy) and the sequence of operations is really confusing.
My take? Despite of having 2-3 year old maps, I will still use Mapopolis. I'm not saying this to grab anyone's attention. It's just the fact that the market hasn't provided an easy to use product that can come even close to Mapopolis. It's not a matter of being flexible and trying new things. It's a matter of having a good product and an intuitive interface.
Once again, Mapopolis is really a wonderful product! Please let this forum know when there is a product in the market.
