Kwaad, where did you get those numbers? See this link:

According to that link, in November 2006:
Emotion chip: $27 (you said $45)
Blu-ray drive: $125 (you said $200)
Cell: $89 (you said $95)
So according to this and your new cost numbers (which I don't know where you got either), the current cost savings would be at 27+75+29 = 131, best case... Now give some sources for your current $50 price of the blu -ray drive please.
