I agree with sixtofour. There's no doubting the fact that ebooks are more "efficient" - from a space, price, and even environmental standpoint. However, as an avid book reader (physical books, I still have not switched over to the ebook readers), there's just something about having a book on my nightstand to read for a few minutes before calling it a night, or on my desk to take me away from my work during my lunch break. On the flip side, I have a million and one things I can be doing if I have my laptop open, and a book just has too much to compete with for my attention.

I'm a huge fan of technology and modernization, but I for one just don't see myself making the switch to ebooks in the near future.
