Prices in the US don't include sales tax. Most states charge sales tax, which is can be as high as 7% like in California. So, the price of the base model in the US is actually $856, assuming 7% tax, compared to 950€. That extra ~$100 is coming from USD strength; Apple had to increase prices globally by $100 because of this to prevent their USD earnings from falling.
Do all EU countries require an extra year of warranty (2 years total) like in Germany? In the US, we only get 1 year of standard warranty. If so, that's another reason why the prices are effectively the same (besides the extra $100 from currency fluctuation).
