I think that the nook requires an American credit card to buy stuff, or at least a billing address.

If you don't feel like reading the whole thing, then I'll just copy and paste the important part here:
"I also really like the ability to load in all of my own content, which many tablets like the Nook and iPad don’t allow you to do. Since I live in Canada, it is impossible to enjoy this tablet to the maximum and international customers are severely limited in the things they can purchase or download for free. This is the number one drawback, and anyone outside the USA should strongly consider this if you are thinking about buying the Kindle Fire HD 7. Of course, there are workarounds. You can simply install the Good e-Reader APP Store and download Netflix, Hulu+, Marvel Comics, Zinio, Press Reader, and other popular programs to get all of your content you couldn’t otherwise access. It’s jumping through many hoops instead of “1 click downloads,” but at the price, you maybe inclined to do it."
I just have to say: If l lived 2 hour's drive south and in the U.S., I would have bought 133 kindle books instead of kobo. But I like kobo, and I recommend it. Sorry that I didn't fully answer your questions, but I hope this was enough to make you not buy a kindle or a nook. I just can't believe that they're ignoring the 34 million potential customers up north!
