It seems like every few years a new e-book device comes out that promises to revolutionize our reading experience, hoping we’ll throw out our book collection and read everything electronically. Recently, the Sony Reader and Amazon Kindle have been the contenders in e-books, but many people complain that they are not open enough for different types of books and that nothing can really replace the printed word on paper — for portability and ease of use. So what would entice you to give e-books a try? Cheaper books, better interfaces, less environmental impact? What features would you want in an e-book? Or if you’ve already been won over, tell us what you like about your Kindle or other e-book reader device. I’ll run the best comments in a future Your Take Roundup post.
