I came to that decision for several reasons:
1. It was on sale for Father's Day.
2. You can put your own photo as the screensaver!
3. It doesn't have advertisements they try to make you pay to get rid of.
4. Most importantly, the piece that plugs the cord into the wall was only $10 rather than $20 for the kindle one. But seriously why do all these companies make you buy chargers separately?! Insane.
I love having one for the fact that I live in the absolute middle of nowhere. The nearest book store is a 2 hour drive. So if I finish a book and NEED the next one, I can just hop on my nook and stop the suffering. And it's good for those novellas that don't always necessarily make it into book form.
I dislike it because all the reviews I saw in my intense research said that it will pay for itself eventually in the fact that books are cheaper... But in my experience that is not true. One book I bought on my nook was actually more expensive than the actual physical book. Maybe if you only shop in the free and 99 cent books, but I'm not about that life. I wanna get all the fun new books!!
Also I would personally just rather have a physical book, but sometimes ebooks are more convenient.
