Indeed. I am a few friends all are what would likely be considered voracious readers. I believe I got my kindle touch about 2.5 years ago, and I've got about 250 ebook purchases in my library now. I also still buy physical books, but generally that's for certain authors/series I've been following/collecting, and it's vastly outnumbered by my digital library in terms of purchase volume.
Why do I like the eReader
* It's just as easy on the eyes as a book. Easier in some cases as font-size is adjustable
* If I finish a book, and there's another in the series, I can just grab it
* Holidays, etc... it's *MUCH* easier to pack an eReader than a half dozen paperbacks
* Most eBooks are priced more reasonably than print, with the exceptions of some major authors
* With the above, I've found a ton of AMAZING authors
* Suggestions based on my reading: which led me to many of the above
Features I wish my eReader had
* Solar charger
* Waterproof
* Backlight tinted for night viewing (non-sleep-interrupting, I don't have a backlight at all on my model though)
* Ability to follow a series. Possibly an author. I'm not sure if I'm just not finding this feature or if Amazon is really missing the ball here, but it seems it would be an extremely convenient feature to get notified of new releases and beneficial to them from a sales perspectivel
I can't comment on other readers because I don't have one. The may have or lack some of the features of mine.
