I prefer a hand held book as opposed to looking at a screen. But, having a computer that can hold all of the weight twenty books that one can hold in one's hands is tough to beat. It has got to be a trade off.
Not all of what I might want to read can be found in a book just yet; just here in the digital space can it be found.
I hope books stick around. I don't like the fact that things can be change digitally so easily. If the wrong sorts of people want to direct the masses more effectively, all they have to do is change some words and say it has always been like it was. (It will drive us crazy knowing how much stuff they change to their liking.) Having a hard copy of a book, the words will not "magically" change anytime soon.
