The price difference is quickly made up for with the re-usability factor.
I don’t think that’s true, CD-Rs cost pennies. You have to rewrite every CD-RW 4 or 5 times before it’s comparable in price. In practice, across every CD-RW ever made, the approximate number of times it is written is probably about 0.5
Yeah but it sounds less cool if you say thirteen point three millilitres than to say Four (4) TRIOS™!!!
