Look, I'm not a fan of reading through tablet/PC/kindle. I have no idea why are you so aggressive when you read something that's your thing.
Also, books aren't that expensive luckily, since people are morons. So I can get great deals for used books, some even new. And lastly, having a private library is like a small dream of mine. I do read a lot, whenever I can at least, but I wouldn't mind leaving that for future generations. Books are the last thing I'd regret spending money for.
