I love eBooks.
I bought my wife a Nook several years ago for Christmas. She was in the middle of a hardcopy book and I thought I'd give it a try while she finished. I was one of those guys that said I would hate them and I need the real thing. Within 20 minutes I told her I was going to have to get her another Nook because she wasn't getting that one back.
I love that you can read a book in any light and that it doesn't weigh a ton even if it's a long book. I love that you can have hundreds of books on the thing. The thing that I love the most is that you can change the font. My wife's favorite book is one I've never read. We have two copies, but every time I picked one up, I quit within a few pages because the font is too dense and small. With an eBook, that's not a problem. If you get a good one, eyestrain is about the same as a real book. I have a Kindle Voyage right now. I like that if I don't have the Kindle with me, I can open the book on my iPhone and it opens to the page I was reading on my Kindle--I always have my phone with me, but don't always have my Kindle.
But perhaps best of all is a good library and the OverDrive app. Free downloads. My library has about eight copies per book, but I've seen a newer bestseller with 105 copies.
About the only drawback for eBooks for me is when you have a book with diagrams or pictures. Then it sucks, but then again, you are reading a book that only you have read while sitting on the toilet.
