Flash will never be cheaper per Byte than optical? Wow, not only is that a bold statement, but I don't buy it for a minute. Optical has already reached it physical limits. While blu-ray is impressive, its the end of the road for the technology.
10x faster transfer rate? Did you pull that number out of your butt? 1x Blu-ray is 4.5MB/s. A bottom of the barrel x13 SD card is 2MB/s. The fastest bluray drive is 12x at 54MB/s while the fastest SD card is x760 at 95MB/s.
Flash has a long list of advantages over optical. The only thing optical has over flash right now is price per Byte. When that changes, optical will finally be dead. For many of us, it already is. BD-R's suck.
