I am not quite so confident. At best it will be manufactured and sold in volumes close to two orders of magnitude less than a mainstream Intel x86 processor and it is built in a more expensive (SOI) process.
I don't think so. By early 2004, a comparable 2.8GHz P4 will go for around $200. With even inflated wafer costs and low yields, I make the cost to IBM at less than $40. I'd guess between $200-$250 to Apple. No more.
