But how many do you need?  The cost difference isn't that great, I 
don't need many level 0s, and -- perhaps most important -- DVD readers 
are reasonably common today, and are standard on most new machines 
being sold in the U.S.  As someone else pointed out, access to a reader 
is important, too.

DVD-R is write-once, like CD-R; DVD-RAM is one of several contenders 
for reuseable DVDs.
