I'll just use one of those ARM chips with 8MB internal memory available from US manufacturers instead; it would make quite a neat arduino-like board. I don't need the phone functions; just a couple uarts, spi, twi... I'll even buy 10 at a time, and spend $10 each.
Got any suggestions?
(More seriously: don't discount manufacturing "IP" and expertise. Being able to build a package with 5 (?) internally connected dies at this sort of price point is a pretty significant feat!)
