I agree. I can't see how semiconductor manufacture can ever compete
cost/bit with optical media - there are simply so many more process
steps involved, including bonding the chip and mounting it on a PCB
or other carrier. One 1600GB optical disk is gonna cost a whole lot
less than 100 x 16GB microSD cards no matter who manufactures them.

200 episodes? I have a lot of catching up to do - I think I would
have seen less than 50 so far...
