I have heard arguments for both sides.
E-readers are light, portable, and extremely convenient. That, in addition to the fact that they do not take up space on your bookshelves at home, have seemed to create a highly desirable set of e-reading products.
That being said, there is also the other side of the proverbial argument. Many people prefer the look, feel, and scent of actual books. Some readers have the tendency to skip ahead or peek at the end of the book before they continue to read, others are avid collectors of bookmarks and require some place to put them. There is also the value that paperback book readers place on their novels, particularly those which have been signed by the author, or hold a particular age.
Then there are people like me. I am a 'both' type of person. I have an iPad with Kobo, Kindle, and iBook apps. I have downloaded my favourite novels, free novels, cheap novels, and many in between. Some novels that I truly enjoyed reading in paperback, I downloaded as well, simply because I could. Likewise, I have found a novel on e-format and bought the paperback because I loved it enough to want a copy in my collection.
I also have antique books in my collection, but those have been placed on a separate shelf of honour. My favourite authors' (of which I have a few) novel collections still grace my bookshelves, as I reread them often, some I've read up to 12 times. When I buy new novels by my favourite authors, I always buy them in paperback, so they may join the others on my bookshelves.
So there you have it. I am an in-betweener when it comes to choosing between eBooks and paperback novels.
What about you? Do you prefer eBooks or paperback books? What sort of e-reader do you have? What do you like about it?
