Integrity and speed are an issue as well, however.
The wave of tomorrow will be bookshelf (notebook form factor) hard
drives that hold 1TB each! Perpendicular recording method drives are
already hitting the market.
Smaller is better, and they are certainly faster than any optical
disc medium.
You just watch, won't be but a few more years, and we all be back
to the most reliable medium. Hard drives.
You go buy a game, and instead of installing the game, you merely
plug the drive in. That way, they ENSURE that nobody is pirating
anything.
