Query: Great! Simply Great!

I have had this for a year and if I lost it, I would buy another one tomorrow. It has greatly exceeded my expectations. It isn't perfect, but 95%+ of the time it is able to find local merchants. If you want to find the nearest Barnes and Noble, plug it in and away you go. With a 1 Gig card, it can hold detail maps for about half of the United States.One limitation is the maps are not all that new.
