Years ago a friend got an iPod, ripped all of his songs to mp3, then wanted to get rid of his large collection of compact discs he had amassed over the years, because they were just taking up space.
I understand what he means, but not having the actual cover with the images and liner notes just isn't the same. I hear people talk about book reading devices like the Kindle, and how they have piles of books they don't need any longer. The same has been said about keeping photographs and movies on their computer.
The idea of keeping such a spartan home would be nice when you are cleaning, or if you move a lot, but I like to hold these things in my hands. Besides, old books smell nice.
