Even the English speaking countries use a slightly different keyboard. The " key and the @ key are swapped round on the keyboards in Britain and Ireland, compared to the US. Some other keys have symbols arranged differently too, but most characters are in the same location.

Because they can.
It depends on what you mean by "great." Amsterdam is the most sexually liberal city in Europe. Laws affecting the GLBT community are more liberal than those of the US in most of northern Europe. Spain recognizes same-sex marriage. Of course, as with the US, laws are constantly being updated.
