Chuck Wendig posted recently about the ebook pricing crisis and sums up this entire thread, pretty much.

It matters little what the e-book actually costs.

It only matters what the audience thinks they should cost.

Now, the audience won’t agree on an actual number (they’re cagey, those fuckers), but what they do seem to roughly agree on is, e-books should be cheaper than their print counterparts. What the e-book actually costs is irrelevant. What matters is the expected value loss by going with an ephemeral digital item — and, further, added into that is the expectation of, “I bought a device to read this, which cost me money already.”
