In addition to being signifigantly more expensive then magnetic media, flash 
memory has a much more limited life time in terms of write cycles then a hard 
drive does. As Bill noted, if you want fast access times, there are devices 
to adapt flash memory to IDE.  There are also devices to allow you to use a 
large amount of battery backed RAM as a hard drive.  The price to storage 
space ratio, however, simply cannot compare to traditional hard drives.
