I love my Kindle Fire. I am currently on my 3rd Kindle (the other 2 are still working--I gave them to my daughter as I upgraded every few years. I still own many books in physical format because I prefer it, but the Kindle is great for travel and for teaching (I have the complete works of Shakespeare and of Jane Austen, as well as the Holy Bible in English and German.) !BBH
Yes, especially for travel. Many times I would like to take all my books in my suitcase to the places I want to go. The Kindle at least gives us that opportunity.
