I'm on an Anthony Trollope kick these days (right now working my way through the Barsetshire novels, nearing the end of Framley Parsonage). I'm reading his works on a digital reader, which is a marvelous device indeed; I recently bought "50+ works" of Trollope online for the princely sum of $5.69, impressive, I think.
I also think this is the future for the distribution of literature. There will always be a market for fine hardbound editions, of course. They are still best way to read while curled up in a comfy chair by the fire (somewhere buried in the family book collection there's a nineteenth-century complete editions of Trollope's works I intend mining for this weekend) but with crappy paperback editions costing upwards of $10 these days, and the price of digital readers coming down, I think we will see their demise relatively soon.
