AtlasCE is nice for an overview, but doesn't contain much meat.
If you are looking for on-the-ground tourist type info, I always recommend
Lonely Planet's excellent web site for info. Saving web pages to your handheld isn't the most elegant solution, but it's the quality of info that really matters, right?
I know there is a huge amount of economic info by country in Business: The Ultimate Resource, which is available in Mobipocket format from
Franklin. While I highly recommend this book, the eBook price is an
INSANE $99 USD. Since I paid $50 Canadian at Costco for this in hardcover, I can't bring myself to pay 3 times that for an eBook version. But it's there if you need biz info on your PDA.
