Most of the cost is in labor to write and edit the book, which still needs to happen for ebooks.

An ebook is searchable, gives me instant access to a dictionary, doesn't take up space in my house, I can read in the dark, it's more comfortable to hold, and I can set the font to a size that works for my aging eyes. That $10 ebook of The Dog Stars is a much better value for me than a $4 paperback copy.

Paper books have their place too. For example, I want physical cookbooks that I can leave open on a stand as I work in the kitchen.

1. I don't have to store all the physical books I would have acquired over the decades.

2. I can carry around a large number of those beloved books with me at all times.

3. I can vary the font size, which my ageing eyes appreciate.
