‘…the ePub format, which is open and freely available for any device, unlike the Kindle’s proprietary format, which functions only for Kindle. The ePub format is used by every electronic reader except the Kindle, and promises to be a big selling point for Google Editions, the search firm’s planned Web-based electronic bookstore scheduled to launch this summer, which will allow buyers to read books and much else on any number of devices. (This may include, by year’s end, Google’s own tablet computer.) It’s through ePub that readers have instant access to millions of books in the public domain, that electronic publishing has a chance to become standardized, and that writers will have more options when it comes to disseminating and selling their books. …’

e-text and e-books are topics I’ve been passionate about since ~1998 when Boris Mann tried to convince me that reading a book on a Palm Pilot could be an enjoyable experience — I never did get through more than a few chapters back then.
I’ve watched with fascination as audio, and then video, not text have migrated to digital. Although, writing has always been the main interface to computing, and digitization it is magnitudes smaller than the other medians, the reading experience has been much harder to improve upon than the listening and viewing experiences.
Fast forward to today and since Christmas (spoiled), I’ve read a half-dozen books on my Kindle 2. I’m already itching for better tech. I’m continuing to eye where publishing goes next, particularly the free culture implications
Sue Halpern’s whole article is excellent, and provides deep insights into e-reading, where the iPad fits in, and where e-books fit into Apple’s iPad business. Her essay is among the best I’ve read in a while: clear domain expertise, wide knowledge (open source shout out), objective, and excellent prose.
I emailed Sue, and she confirmed for me,
“DRM [(digital rights management) protected] books don’t go anywhere– yet. I think this will change when Google gets into the game. Right now epub on new books mainly benefits publishers, who don’t have to have books digitized in numerous formats in order to be read on various devices.”
