I have a Nook and loved it until I got my IPad. Now I much prefer reading on my IPad. My Nook isn't backlit, and I love that I can read on the IPad in bed with the light off, and just let it turn itself off if I fall asleep. I love checking out the e-books from the library. Isn't technology wonderful!
My backups are kept up to date on a regular basis. I have all my scrapbook items backed up on an EHD, which I update about once every couple of weeks. I also have Carbonite, which saved me once, when my hard drive crashed. I am very comfortable with what I am doing for back-up.
