just because you don't use the optical drive doesn't mean others don't. I know a number of people that use them for dvd authoring also getting digital copies of films and ripping music/movies of the disc.
I think the big deal is, why remove something in a desktop unit that doesn't need to be light and thin? consumers and professionals that have a ned for the drive are left in the cold now, especially with mac pro's being prohibitively expensive
So you have to buy instead of steal?
