I'm... 50%-50%! :)
Working on the book industry, maybe my experience goes a little further than the "like/dislike/prefer/hate" (by the way, as a reader I use both with no preference. If I'm around and see a book I'm interested in, I go and buy it - if it's not too expensive. 22€ for a hardcover fiction book is WAY TOO much! And if I want to read something in English, the American online stores have "piles" of books to choose from, and the best thing is that you canstart reading in minutes)
"Professionally" speaking... God bless the e-readers! :)
Consider this: you're not American/English and a big part of your job is reading foreign books to decide if translating in your home language (Italian, in my case). Before the e-readers were reality, you had to read everything on a monitor or print pages and pages of text (and consider what happened if a book had to be read by more than one person). You could also request to agencies or foreign publishers some reading-copies of the printed book but:
- 8 times out of 10 they replied to the mail just attaching the PDF
- 2 times out of 10 you had to wait for them to prepare and send the book(s) and for the postal service to do its job (oversea shipping takes a loooooooooooong time, and nobody wanted to pay for express delivery, which was - and still is, I suppose! - expensive as hell)
Now, you can just have the PDF or DOC or whatever it is in few minutes - it's just an email - convert it if necessary and read it on your ereader, without killing your eyes in front of a monitor or printing piles of sheets of paper.
So... as a "job instrument" it's not just handy, it's a lot more.
Again, as a "regular book reader", I don't have a preference on p-books ("printed" or "paper", you choose!) or e-books. What is important is having something good to read.
Last thing: I'd kill (I joke, of course! :P ) whoever says "I love the smell of the printed paper and can't live without it"! :) It's true, it's a particular smell, but try to go and pick up a 10-years-old book from a public library, better if it is a bestseller which has been read by many people and got a lot of dust staying in the shelf for such a long time. The "lovely smell" becomes a "rancid stink"! :-P
... and, talking about ebooks, it's not all "good news": a failure of the internal memory of the e-reader and/or a bad backup can destroy your library!
That's why both formats will survive, in my opinion! :)
(as usual, sorry for any small/medium/bad/horrible mistake with the English language. I do my best!)
