Hmm, I am from Germany, too. I don't have a Kindle, but I use the Android and other Kindle Apps and I have purchased several books and even a magazine subscription using my german credit card (and never gave them an additional address in the states). Also, I can sign into Amazon.com using my german Amazon account, I don't remember when they changed this, but at some point it just worked. I am not going to move to the German Amazon Kindle Store, as for example that magazine subscription is not available in the German Kindle store. To me, that is the real problem at hand (besides the fact that they shouldn't expect you to pay the same amount of money for a digitally distributed version as you would have to pay for the dead tree version, but that's a totally different issue, which has already been discussed a lot).
