In reality I believe the initial value is closer to $20. They have said that Bay Trail Type 3 reduces it to 1/2, so that's at $10.
Regardless, the whole point of my post was that the platform is price competitive with Mediatek. I know how much an SoC should cost, approximately $20. So if they needed $15-20 Contra Revenue to reach $27, my post wouldn't make sense, because it means they would be selling it at $42-47.
Bay Trail with LTE is said to cost $47. Mediatek MT8382 is $39.9, but with 3G. Bay Trail costs more, but it has LTE, which will command a premium. That points it as a rough price parity.
