Well, you usually get what you pay for. Ranting about poor descriptions of free software seems just a tad juvenile to me, but maybe that's just me.

Maemo Mapper is much better than the built-in program, and you can get all sorts of maps, including satellite photos. Try different sources for the maps and see which you like the best. I like the VE street maps, myself. It's just not possible to fit all street names on large-scale maps, there just isn't room. You have to get to a scale which gives room for the street names. I think you'll find Google or VE maps do this better, though.
