I still keep 10 or so of my favourite books in print form, and admittedly they do act as decoration more than anything (I have read them), and occasionally buy a print book when no digital format is available.
I know I can't resell the digital books, I can't transfer ownership of them, and they may (unlikely) be censored or removed from my device. I still don't care.
It's so convenient. Travelling with 1 thin Kindle in hand luggage as opposed to 3/4 brick books in my suitcase, the immediate page turns breaking the read less, the backlight for darker situations, the ability to get it in a thin pocket and get it out and read wherever I need to kill a few minutes.
The complementary phone app is also really useful when I don't have the e-reader on hand. I've been doubling my phone up at the gym as a workout logger when lifting and book when using cardio machines like the static bike.
The issue I've always had with books is the idea that when I buy one, I think I'm buying the time to read the book as well. When I go to book store and see dozens of interesting books, I often forget the weeks it will take to read them all. I get through 1/2 books a week and there's a mountain of stuff I want to read. Little optimisations in getting more time to read really help with that.
