Selling more e-books than hardcovers

According to the Wall Street Journal, Amazon reports it has sold more e-books than hardcover books over the last three months.

This may seem impressive…but I’ve always thought hardcover books were a terrible deal anyway. In what other market are you offered the product initially and then months later consistently offered the same product at half-price?

Also, I still don’t feel compelled to buy a Kindle or a Nook or an e-reader.
