I have a Nook, and the huge issue is that you cannot download books here in Argentina (or outside the US) as there are copyright legal issues. I am sure Amazon will have the same problem.
However, there are some work arounds.
1, Technical one: if you are computer savvy you can (i believe the term is "spoof") your IP address so that the computer thinks you are downloading in the US instead of here. There are paid services that you can sign up for, and probably free ones. This has advantages in that a lot of websites that block content due to copyright issues outside the US will now be available (Hulu for example). Downside is, a lot of these websites are constantly guarding against these spoofing tactics.
2. Give a friend you trust access to your amazon or whatever account. With the Nook if you purchase in the US through your account, you can download the book once it is in your account anywhere in the World. I know it sounds all very 1991, nascent internet, but "thems" the rules. Upside: books galore for less. Downside: You have to bother your friend for it, and hope they do not purchase round the world plane tickets on your credit card.
so far, when I have time I am happy with the Nook, and supposedly the new color one is even better. Only downside is it did not really solve the "reading in bed problem" as I still need an external lightsource. Screen does not light up...which is good for long term reading/eye strain issues, and battery life.
Also, still a bit "old school" in that I like the book. But the ease of acquiring books, and cheaper price makes me more eager to get books to read. Also if you travel it is a huge bonus. Plus you can download newspapers or magazines which is nice if you want to read on a flight or long bus trip.
