I think he's assuming that a 4GB CF is a 4GB micro drive in a CF form 
factor.  There are both mechanical and solid state versions of 4GB CF 
cards.  Some people were using the micro drives from mp3 players such
as the 'ipod mini.'  I think this is what he was referring to rather
than
a true flash memory device that you are thinking about.
