technology will always dictate the speed and quality of the finished product, hence how vinyl evolved to cd to mp3
Ironically, serious music lovers have always thought that analog equipment (both recording & playback) are superior to digital. I always assumed that the music recording technology was improving, also, but learned a while ago that the quality of an MP3 is good if you listen to one type of music: pop. But if you listen to complex jazz or classical, the quality deteriorates. CDs are way better than MP3s, but still lack the depth that vinyl has.
Perhaps it will be the same for electronic text files. After all, the appearance of cheap pulp paper allowed publishers to come up with "penny dreadfuls" and "dime novels' (most of which are horrible). Perhaps the same sort of thing will happen with electronic texts--already we're seeing an explosion of "self-published" (read: unedited & mostly unpublishable) ebooks. Who knows what awful writing future e-readers will be subjected to? (Of course, it can't be much worse than the stupid stuff people put on their Facebook or Twitter profiles ha ha!)
But the ability to sell something without actually producing anything looks very attractive on paper. In reality, however, musicians aren't making money unless they're touring, music stores are all but closed. Will books follow the same pattern? I for one, vote "no."
The honeymoon for the Kindle is over, and I suspect Amazon will stop manufacturing them in a few years, and just promote their Kindle app for the iPhone or iPad. No one really wants to spend a hundred+ bucks just to pay too much for an electronic file that they can't sell when they're done with it. It was a fun little toy, but already a Scrabble game is a best-selling product in the Kindle store.
Serious readers want a book. And the superiority of books over electronic files is not even questioned by the ebook manufacturers.
