cd roms are a thing of the past now , they have stopped pretty much at a top speed of 56x or something like that ..everything now is going to dvd's. its the difference of being able to store 800mg as to 4.7gig of info on one disc , also note that the new ones are now dual layer dvd's which is even more storage. with a dvd burner , if you wanted to do a back up of your hdd , on a cd you may use up 4 or more , where as with a dvd you would only need 1 dvd .
or if you wanted to make a home movie off your camcorder you could with a dvd and the quality would be great .
if its not artifical intelligence, why have it?
