Don't get the undies too twisted.

I said it's silly. In the context of FR, setting-jumping makes some sense (even if it's always been some of the most extravagant silliness of the setting). In the context of Eberron, it makes a lot less sense. It's a rather blatant attempt to capitalize on Lolth's and FR's popularity by jamming them into a very different setting. Eberron's Drow are a different beast than FR's, and have an awesomeness all their own. Instead of trying to realize their own awesomeness, they decided to import FR's. Which is a little narmed.
Of course, I'm of the radical opinion that just because someone thinks X is awesome is no reason to jam X where it doesn't belong.
