For me, the feature I really need is the route drawing tool where I can easily draw any route line and it gives a profile with mileage and elevation gains and losses. Just getting a free scanned map is not sufficient. I also like to be able to get coordinates off points, and add text, symbols. I also like the state coverage. I use TOPO to search for areas that I may want to go to. TOPO, for me, is better than a good novel to entertain me on those cold winter days! I assume that some other company will pick up the ball and offer the same features. It is although quite annoying to think that my TOPO program will soon be useless. Seems that this is typical of compter technology nowadays- come and go. Always have to "upgrade" your initial investment. We certainly live in a "throw-away" society.
