As you guys have probably heard, Amazon …

As you guys have probably heard, Amazon has reported spectacular growth of its Kindle business. Sales of Kindle hardware tripled after the recent price drop to $189, suggesting that a genuine tipping point has been reached.

More interesting, though, is the fact that e-book sales have now overtaken hardcover book sales, at least on Amazon. I can’t help thinking back to the early days of the CD format: CDs started to become widely available around the mid-1980s, and officially overtook vinyl LP sales in 1988. No one expected the LP to be eclipsed that rapidly; and now we may be seeing the same thing happen to print.

If the analogy holds true, within a few years we’ll see the emergence of a vocal contingent of bibliophiles who refuse to make the digital transition. They’ll insist that dead-tree books have an “analog warmth” that e-books lack, and if we were only sophisticated enough we’d be able to sense it too.

And besides, e-books just fill your head with numbers, and that can’t be good for you.
