Not to resurrect a dead thread, but I just downloaded the "Free" application as well as the blue marble map and a sample topographic map. Both are somewhat disappointing without a zoom function, but I have high hopes for the $29 version of the Arizona map. I think they may have slashed their pricing structure too since every state is now $29 for a download and $39 for the DVD version.

Now I'm just waiting for them to send me the download link and I'll really put it through the paces...
