First - Go read this great article from Time Magazine: Books Gone Wild: The Digital Age Reshapes Literature. (Well worth reading.)
Second - Stop and think about it for moment. Computers and digital media are changing everything we do these days, whether we realize it or not, and that includes our beloved books.
To be different, today, we're having a discussion in the comments section of MizzB's blog. I've participated in the discussion and I'm also posting my response here.

That being said, I was diagnosed with a retinal disease many years ago (Retinitis Pigmentosa) that is gradually stealing my sight. I’ve read reports stating that products like the Kindle are helpful to people with eye issues becaause of the ability to change fonts, etc. and that the screen is easy on the eyes therefore, creating less eye fatigue. Because I am legally blind, but I still have tunnel vision which enables me to have center sight, my eyes do get incredibly tired faster than most. I will no doubt invest in a Kindle at some point, but I will always prefer a tangible book.
The same goes with audio books. I do have a few, but I find it difficult to focus and concentrate on the narrator. I’m sure it just takes some getting used to. At some point, I’ll have to use audio books, but I’ll jump off that bridge when I get there.
