Hi, I am considering getting the Nokia N810 Internet Tablet but there were a few things about the Wayfinder software included with it that I couldn't find the answers for. Could someone who owns one please clarify for me:

1. They list countries that maps are available for here: http://www.wayfinder.com/?id=6185&content=map_coverage
Do these all have STREET-level detail maps of major cities in those countries? Roughly how much storage would USA + Canada take up, for example?
2. Can I enter a street address/postal code and find it on the map for free (so not get directions TO the place, but just see the final destination)?
3. I'd really like a complete list of the POI categories in the database (this could just be a screenshot of the selection list when you
do a POI search).

Thanks in advance!
