I hope it doesn't happen in my lifetime. I hate reading on line. (Other than the short editing & tranx I've done.)
But what is it that you hate about it? Is it the eye strain? e-Ink would fix that. Is it because you have to sit at the computer? A hand-held, paperback size device would fix that. Is it because the font size, etc? A device that has adjustable font sizes would fix that. Is it because you want something to hold and have the feel of paper in your hands? Future devices could change that.
Sometimes, never say never. I know Stephen Spielberg said something about DVDs about five or six years ago -- that he would NEVER embrace digital videos. Well, he changed his mind (well, sort of... he still does his editing on an analog machine despite the advancement in non-linear digital editing... he admits that he's a dinosaur when it comes to technologies -- that's a shocker considering he's the guy who brought ups ET, Close Encounter, and all those sci-fi movies).
I, for one, would LOVE to have a handheld device that gives me instant access to information, search capabilities, indexing, bookmarks, etc. -- NONE of that available with print. I would give up the look and feel (and nice smell of books) for that kind of convenience. The iPhone is very close to that nirvana, except the screen creates eye strains.
I mean, some people, in 2009, still say they won't download music or videos, etc. They would rather have a CD in their hands. I can understand that -- people who grew up with watching films and listening to LPs don't trust these "digital files." But more and more people are switching over, though. I've known people who have listened to nothing but LPs and cassettes now are download music from iTune because "it's so convenient and they can just download what they actually want." And they can take the music anywhere, or play it on any devices they own. No CDs to break. No need to carry them around. So, I have seen "dinosaurs" actually embracing the new technology.
So it comes down to this: What can the technologies do to make it easier and worthwhile for the consumers?
In order for eBooks to go the way of digital music and videos, they have to overcome these:
a) convenience (I think they're getting there with instant downloads, the form factor of the eBook readers, etc.)
b) price
c) durability (I think people can adjust to that -- people aren't going to throw their iPods onto the pavement or toss their iPhones on the ground... but yeah, you're not going to be able to dump the thing in water as you would be able to do with books).
d) user experience
I think D is the sticking point. Part of the beauty of digital music and video is that their qualities are continuing to improve. Watching an HD video is better than watching it at a theater sometimes. Digital music could have greater fidelity than CD audio (what with oversampling and surround sounds, etc.)
But how can you improve on the experience of READING?
I think we're on the right path, though. I recently "read" a flip-book online and it was really neat. To me, that bridges the gap between my experiences with books and magazines and the online experience. While I still like to be able to feel the glossy paper, the convenience seemed to make up for it.
