Let me just add Peter Naur to that list since I'm Danish myself :)

Where, exactly? If you expect classes in English, then you betta' stay/study in the USA.

I'm from Denmark, and I graduated in computer science a few months ago from the University of Aarhus. All courses after the first year are required to be thought in English. Heck, we use American textbooks in most of our second and third year courses. But hey, if you ever come to Denmark, then don't spend all your time studying. That's not what going abroad for 6-12 months is all about. Make some new friends, go drinking and partying, pass your courses of courses, and come home with something cool to put on your CV :)
