I have still yet to see the value in spending hundreds of dollars on a device for which you still need to purchase books, in Amazon's case at full retainl price though they don't actually have any material cost or disctribution cost, and that may have at best a limited lifespan. Further, they're DRMd and can not be shared as traditional books can be, it has limitations of a battery, can't be used outdoors for extended periods in summer heat, is susceptible to wear and tear, droping, liquids, and theft.
If e-books were $1-2 for editions available in paperback, and $5-6 for editions only available in hardcover (for the early adopters), and if they came on a system easily portable and sharable file format, and had guarantees in place that when a new technology comes around, all existing purchased books could be migrated free to the new format/technology, then MAYBE I'd pay $60 for an electronic reader... Still, even as a avid reader, I'm lucky to churn through 20 serious books (600-1000 pages each) a year. A device might, if i took good care of it, last 5 years, with at least one battery replacement over that time.
A book lasts my lifetime. I also tend to buy hardcovers, especially at bulk sales, so I'm typically paying $2-7 a book. 20 books a year times another 50 years is I'm lucky, times a fair average of $5 a book (excluding inflation), means $5000. If i have to replace a $150 or so device (including batteries and accessories) over that time every 5 years, then that's $1500 alone (again not including inflation). That means the electronic copies, just to be worth it for my readin habbits, need to be $3.50 max each (on average). This also assumes my above complaints that the books need to be protable, sharable, and are freely migrated to each new compatible format.
It just does not make sense!
This is besides the aesthetic appeal not only of having a real book in one's hands, which can not be beat; the potential of having the real author sign my book (several of mine are signed) dramatically adding value; the appeal of having shelves of books to show off to company and say "yes, I've read all but a few of those", and the visual aesthetics that a properly filled bookshelf brings to a room... i just do not understand the appeal of the digital book, especially with such a bulky, expensive and fragile proprietary device...
