To me, there are benefits and drawbacks to both. If space, convenience, and money were never a concern, I think I'd pick conventional books every time. There's definitely a charm to the printed page that you can't get from the screen. I love the covers, the lettering, the feel of the pages, and the way that you can flip through them.
But, technology has a lot going for it these days. Now, I can carry several dozen books in the same size package in which I could only have one or two before. If I want to get more, I don't even have to leave the house. I can just download a new one and if it's in the public domain, I can do it for free. And, I can pick the size of the lettering to suit my needs. I don't have to stick with the one size that I can get on the printed page.
Also, back when CRT monitors were the only other option, printed media had a distinct edge in being easy on the eyes. But now that LCD screens have matured and Digital Ink is starting to catch on, that edge is far slimmer.
