In most of the pages in Magento, we can find the "State/Province" before the "Country" field. Since the "State/Province" depends on the country, that is confusing since the customer has go to next field and select the country, and then go back to the previous field and select the state/province.
This is not correct in the most important page in the storefront, the onepage checkout:

In other pages, like the shopping cart page, the order is correct:
It would be better if the country can be selected first, then the state/province and finally the ZIP/Postal Code (just like the shopping cart page).
