Two years ago my DVD player broke. A year ago I replaced by laptop with a macbook air. No CD drive anywhere in site. And I've hardly noticed. I don't even remember what DVD's look like. And as somewhat of an apartment dwelling transient, I don't mind the open shelf space, and lack of another box I have to haul around in life after DVDs/CDs. I think generations will look back at the way we stored information and think, "what a waste of physical material".
