Dell's discriminatory €6

A sibling of mine is looking for a laptop to purchase. After looking at Apple's Powerbooks we checked out Dell.
Dell Benelux is charging €6.05 more for a system with Windows Vista in French rather than in Dutch. They briefly explain that they pre-install Dutch Vista on all systems and that doing so in French is extra work for them. This is rather discriminatory against French speaking people in Belgium. When I ordered mine, I did not get any extra charge for an English XP.

In any case, it’s a shame their doing this kind of thing. Whether it is Dutch, English or French, neither should be more expensive. Those are pretty standard in Benelux. I'd understand it if it were for a distant language like Themne or even Spanish.
