Not even the distractions of the phone and all that, but I also enjoy the feel of the paper. There is a tactile connection with physical books that you just don't get with digital. I've even heard rumours that super rich elite types won't let their kids have smart phones and tablets and that elite schools use paper books because your brain is able to take in the information better from physical print. Not really sure if that's real or not but I know I get way more out of physical books. As for getting rid of them, yeah sell on Facebook marketplace or whatever your local buy/sell thing is, it's worked well for me in the past, but really depends on the book. Obscure stuff is hard to sell, but you could always try used book stores, I've had success with that as well.
