I have it and find it semi-useful. Topos are notorious for being out-of-date (nothing like driving to a supposed trailhead and finding a subdivision) so it's good to have an update. However, many roads are missing or simply labelled "Unnamed Street" (I don't know if they have names or not, but it's not very helpful). Coverage in Washington seems much better than Wyoming (missing many FS roads). It's certainly more detailed than a gas-station map, and it's probably as good as a DeLorme Atlas and Gazetteer (paper map book). I wouldn't choose this for city driving. If you're using NG Topo! state, then you're probably better off buying the NG Streets & 3D View upgrade, which includes all of the street data (but not the level 4 maps for the US) for $20. http://maps.nationalgeographic.com/topo/streets.cfm

I use National Geographic Topo! state software and it works great. It's easy to trace out routes for a quick elevation review or to print on a map, it's easy to load waypoints to and from my Garmin (serial) GPS, and it's especially easy to print the maps I want, at the scale I want, without stitching together TIFF files or screen snapshots. It also allows me to easily save sketched trails, notes, and other stuff for reference on future trips. I've found that NG's topo maps are often more recent than the topo maps on the free sites (15 years newer in some cases). Whether it's worth $75/state depends on what your time and effort is worth, I guess. I use free stuff too, but mostly for states I don't have in NG Topo!. I bought DeLorme Topo USA 5.0 and hated it. You can plot contours as tight as you like, but it doesn't avoid the fact that the underlying x-y grid is spaced too far to be useful at field scales. Cliffs look like smooth hills, that kind of thing. It's good enough for driving to the trailhead, but past that...it's not something I'd use even for hiking. DeLorme has a higher-resolution topo product, but it's about as expensive as NG Topo! and it appears to have the same DOS-like user interface. Yuk. The NG Adventure Paper works as advertised. It's made of Teslin, and the ink is permanent and waterproof. I normally print my maps on plain paper and keep them in a plastic sheet cover because it can be hard keeping a half-dozen sheets of paper from scattering anyway. But I've printed maps for some hikes I do often, and even after being folded in quarters and stuffed into my sweaty pocket for a dozen trips, they still look great. I just rinse the mud off afterwards. As far as paper quality, it makes a print that's as sharp as regular paper. Here's a map I made with NG Topo! state. 2.5MB PDF. http://www.lava.net/~dfrick/misc/HonoluluMauka.pdf
