My 0.0002 cents. And I hope Tom isn't offended.
I don't like it. And I'm not above 30. Sorry to dissapoint, BlackSamurai.
Sure it looks cooler but at the price of user friendliness. Readability is quite bad, those small white fonts not helping. I like my websites with a white background. In fact anything with a high amount of text should have white (or light coloured) backgrounds. And when you have a dark background colour, you lose a lot of colour options to use for your content.
Anyway, I hear this isn't permanent, is it? That it is just for the Super GT thingie. Hopefully so.
