I got into e-readers when the first Kindle came out, and have owned at least one ever since. In the intervening years, as the effects of CP have become more noticeable, e-reading has become my first choice. Reading dead tree books is an absolute last resort, only for a literal "must read" that simply isn't available in e-format. I actually bought and tried reading Robin Buss's translation of the unabridged Monte Cristo in paperback, but was simply not able to hold it. Ditto A Suitable Boy.

E-readers let me read with one finger, my "page turning" finger. They let me have several books on the go at once and always with me to choose from depending on my mood, and of course, it's trivially easy to load up on and carry an ample supply of books for the road. With vanishingly few exceptions (I currently own only two), I don't care AT ALL about the physicality or aesthetics of dead tree books. I'm unmoved by the "mystical feel", or the "indescribable, irreplaceable magic" they are said to possess. For me, the content counts, not the medium. And for content delivery, at least of general fiction, e-readers win hands down.
