I have a question

iTunes 4.5:

"Apple will also include a Lossless Encoder in the new version of iTunes so users can 'import CDs into iTunes with sound indistinguishable form the original recording but at half the size.'"

My question is, if they can make them half the size without a loss of quality, why don't they make them half the size to start with?

On second thoughts, I don't want any 2-hour albums, thanks.
