Seth Godin says it better then I do.

The ebook is a change agent like none the book business has ever seen. It cuts the publishing time cycle by 90%, lowers costs, lowers revenue and creates both a long tail and an impulse-buying opportunity. This is the most disruptive thing to happen to books in four hundred years.

I have to agree, although as a previous bookseller and physical book lover this is hard to swallow. But I suppose all I have to counter-argue is emotional base. Like someone who really loves commuting and gets offered a tele-commuting job. Not worth bothering, the train has left the station.
