Books vs ebooks
Power nerd that I am, I own a Sony e-reader. It's a great little device. Its small, it's light, it can last for a long time without a recharge, and it holds bajillions of books at once. Thanks to e-ink, you do from time to time forget that you are not reading a printed page.
While it is a great way to read books, and while I'm sure future e-readers will be even better, it's not going to kill dead tree publishing. Most of the advantages of a hand-held electronic device just aren't that useful for conventional novels. Sure you can hold a million books at one time, but most people I know don't read three or four novels at once, they pick just one and finish it (or toss it against a wall in disgust). Dictionary and search features are nice, but being a semi-literate guy, I don't feel the need to lug around a dictionary so I can look up words from the new paperback I just got. Search features? if the novel is so complex that I have to constantly flip back and forth to figure out which character is doing what, I'm going to toss the book long before I resort to trying to google through it.
The thing that e-readers are good for is increasing the availability of books. With an e-reader, I can read authors that are a little more difficult to find in a Barnes and Noble. Its the main reason that I got it in the first place.
Even if you throw out all the advantages printed novels have over electronic ones, there is still something inherently cool about reading physical books. Just like there is something cool about attending a concert, even in the age of the ipod, or watching a play instead of a movie. Printed matter has been with us since the papyrus in egypt, I doubt its going any place soon.
