I haven't looked up N9 price a lot recently so i don't know how fresh this price drop is, but at least 3 months back the price has dropped over 100 euros.

64GB N9 now sitting at 399 euros in Finland. Probably quite close the price it should be at this point, still it's 200 euros drop from the release price.

Verkkokauppa.com still has the white N9 for 529,90 €. I would think that's just temporarily. White N9 costed as much as the black 64GB when it was released here in Finland.
