I find myself using music metaphors all the time, but this is too perfect, I feel like. Digital downloading is like photographs online. It's great, they're available, you can see lots of different work, but it's a limited experience of the form. A book is like an album. You don't have to have a million dollars to be able to buy it, you have to save some money, you have to buy your album, then you take it home, and you put it on your turntable.
