to chuck out old discs than to go through the hassle of RW.  A big factor
in that conclusion, however, is the need for transportability.  Some
readers have a hard time with RW discs.  You probably know your own
hardware; I didn't always know where it would have to be read.

But I still think the media costs (unless they've dropped) were too high
per performance for RW.
