As a Canadian north of the border, we have had to rely on the US Kindle store until now. This meant we had a US centric portal with limited Canadian content and all transactions were conducted in US$. Amazon has finally opened a Canada flavoured version,were Canadian authors are prominently shown and we can pay in our own currency. 

Too bad we still can't get the full Amazon experience (many of the products sold in the US are not yet available in Canada, we can't buy the Kindle Fire HD, we don't have Amazon Prime, etc).
