Please tell me how much money would you pay to have this accessory for your XBox? Then please look around for a high resolution webcam and see how much is the price.
Even if any of your arguments made sense, let's ask this: If before the ps3 came out we asked with its features "how much is the price", would you still be insisting like you are now that the PS3 couldn't possibly exist because your calculated cost of the components did not equal the target price?
You seem very very invested, in spite of massive evidence in contrary to all of your posts, in proving, in spite of the now dozens of hands on that contradict you, that this is just not possible.
I wonder why that is?
