I have over 300 hard cover books and 5 book shelves to accommodate them all and that made moving hell, lol. No more hard or soft cover books and the Nook was my cure.
I loved the Nook but lost two at airports. I was going to get a third Nook but got a 5th gen. iPad instead because the upgraded Nook was a Samsung tablet which I didn't care about buying. The iPad has been a great portable library for me and the extra programs like the Home, Ring, Plex apps and etc...made me happy to get the iPad back then.
The pros and cons of digital media, the death of indie bookstores and mom and pop stores is another topic.
