Because we all know what happens if we're not the customer.

I have this; I bought it because I want to reward the author for producing a quality work, and because I want to encourage the publishers to produce other works that would appeal to me.

I also happen to like physical texts so I bought the paperback but I have this and the digital edition. The latter is convenient for when I am travelling and appropriately formatted for an eReader (not just the raw html from these pages).
