yes, you are right it is purple. i had 5 of them they are all purple. older berries are either white, or yellow like the 9780 (yuck). finally glad they switched to nicer back lighting. anyone that has a macbook pro, check your keyboard lighting its the same color, very purple.
I think it looks a bit blue-ish compared the really white 9000 backlight. I hope people do not start using magnifying glasses and start complaining of the plastic grain. Purple, blue, unicorn, tie dye, who cares. As long as its bright and usable at night I won't care!
