I found a second article on the Huffington Post that I'd like to share. Jennifer Hannever has taken an opposing viewpoint to J A Kornrath.
Books are not going anywhere. Neither is publishing. Since Gutenberg made his epic contribution to the human race, publishing has secured a place as one of the largest and most profitable industries in history. In that time, publishing has adapted to major technological changes, survived economic meltdowns, persisted through political censorship, and made it to the other side of catastrophic price wars. The likes of Simon & Schuster and Random House are not going to lay down simply because more than 25% of their potential customers bought electronic version of books instead of much more expensive, hard to warehouse, and returnable physical books. If the mainstream publishing world's enthusiastic embrace of eReaders is not evidence enough that they are doing fine, than their stable sales through the largest economic disaster in our nation since the Great Depression should be.
