These machines do not have an optical drive and it looks as if Apple may make this a trend in other models.
Wouldn't surprise me. They shipped the driveless airs with USB recovery recently. Really, what's easier to use, media on a flash drive or optical drive? I'd rather buy something on a flash drive personally. In 10 yrs our big filing cabinet drawer full of software boxes will have been replaced with a coffee cup on the back of the desk full of flash drives.
