For access to books, both the Nook and iPad allow for access to different formats but I feel the iPad may still be ahead of the game. As far as the KIndle? We will see.

Comfort? I am more comfortable reading a printed book. I enjoy holding it in my hands. I like not having to worry about battery life or access to electricity. My books weigh less than an iPad. My eyes are less tired after reading a book (text) than reading en ebook.

The big draw for an ereader is being able to “carry” more than one book at a time and have access to e-mail, apps, and other technology. I also have a Droid and I can do all of the above on it so having a separate ereader may not be necessary. The problem with using the phone is not with the phone but with my aging eyes! I am already wearing reading glasses and reading a book on a 2 by 4 inch screen is taxing. Although, in a pinch the Droid is awesome!
