I love books but my ADD gets the best of me a lot. Even a 30 minute show loses my attention. I'm more of an Internet person because I can change the page every five seconds. Since that wasn't an option, I went with the TV I can change stations on.
I prefer to read various things on the internet (or a book, if I get my hands on an interesting one) and when it come to the telly, I'm reading anyway. I require closed captions or subtitles all the time. XD
Since I don't have cable or satellite right now I spend way less time on tv. We use Netflix. If there were a choice and I could have any book I wanted or watch what I wanted books would probably win hands down.
