Hi I'm from Canada and just bought a kindle. I love it! The ebooks are still super cheap when compared to real book prices and you can get tons of free books as well around. The price that's displayed in the kindle shop for me is already altered to the price I'll pay. Think about it, when you look at a card or book, a paper book will be like 30 to the 25 us, which is always way more than the dollar conversion. A few books I was able to get for 3 dollars and you can have sample chapters and free trial magazine and newspaper subscriptions. I even got a trial of a view pages of a graphic novel, which, surprisingly, looks pretty good!
I wrote a review here:
