E-book of Dan Brown's The Lost Symbol outsells the hardback on Amazon

With a romantic touch, maybe we can consider this day being the beginning of a new era in publishing: E-book of Dan Brown's The Lost Symbol outsells the hardback on Amazon.

This is not a small accomplishment. I hope that it is a true indicator of e-book reader usage and what can be achieved with an appropriate pricing model. I'm sure people are going to argue about publisher's margins etc. but there are more and more e-book readers sold. It's a healthy market. We just need to solve a few important problems (such as appropriate pricing, DRM and common formats) for it to become mainstream relatively quickly. But for now, I'm savoring the moment.
