Wikihood is a very cool app for iPad. It uses GPS to determine where you are and shows you info about all nearby sites of note. Works great for road trips, of which I'm very fond. I also use regular Wikipedia for a lot of stuff while traveling. The city entries often are robust, offering demographics, history and much more. I love to travel, explore new places without planning (that's part of the fun for me). 3G is great for that, and much else, including looking up unfamiliar things (any time, any place) as you read. I often read nonfiction and news and end up finding things on Wikipedia. Often, I'm just googling something unfamilar and will find a good Wiki entry. The info is not gospel, but it's generally good.
