Do you want to know why this has me worried? This article has technical details that only an insider would have.
FFS is the screen tech that is used in the NookColor. I'm sure you know that the NookColor has a high quality, high resolution 7" LCD screen. E-ink developed the technology in the NookColor's screen and they license it to other manufacturers. For example, LG Display make the NookColor screen.
When a source with a manufacturer says that the Amazon tablet will be using the NookColor screen, I'm willing to consider that I might be wrong.
