Follow those links (theres 28 images of that party) and you can see that this was the same Hollywood launch party that Paris and Nicky Hilton were at, and that Paris is clearly carrying the more valuable gift bag with a 360 in it (big surprise no? ). I don't care really, I just wanted to end this pointless argument.
It's called merchandising. If they give a 360 to each of those fabulously famous people, then it makes their product look cool to all us simple folk. If only for the opportunity to snap a picture of them walking away with their gift bags.... it makes them money.
Those were the line of 360s that crapped out on people. Remember, the first wave? Well those are what was left, they had to clear the shelves for the second wave.
