Another thing, upgrading the hard drive and adding wireless added VERY LITTLE to the production cost of the PS3.
The internet consumer price difference between a 40GB hard drive and an 80GB hard drive is 10 cents (I can't find 20GB drives for the comparison, but the difference would not be much bigger), and I'm sure the added Wifi wasn't a huge cost to Sony, I'd guess they maybe added $5-$15 at the most.
