Erica Sadun is right: There's no going back.

I also did something I had never done before. As I was reading the book, I stumbled across an unfamiliar word and, rather hilariously, ended up tapping the printed page until it finally occurred to me that the book wasn't going to offer me built-in dictionary and Wikipedia access.

It's odd how three years or so changes you. Although the Kindle debuted in 2007, it wasn't until 2010 that I really jumped on the e-book bandwagon. My entry was due to the iPad. In fact, it was the iPad 2 even more than the original that firmly grounded me into the e-book world. Between the light, thin design of the tablet and my aging eyes, the iPad with its built-in iBooks app and the add-on Amazon Kindle reader app, I have become a devotee.
