I disagree, because for a couple years my high school experimented with a setting that encouraged use of computers for everything and had no homework, and after a while I realised that it just encouraged laziness and did not teach discipline at all.

I was just playing games and surfing the internet every time I thought people wasn't looking and in hindsight, I really regretted the lack of structure when I went through regular high school later on and had all sorts of attitude related study problems.

It's a fun gimmick, sure, but looking at how overly attached people already are to their smartphones and how difficult it would be to really prevent people from only using multimedia for their intended purpose (there's always a way around everything), I don't think it's a good idea at all.

Books might be heavy, yes, but iPads and other multimedia devices can crash or break, servers can go offline and data can become corrupt, both on servers and on local storage media, and what are you going to do then, if disaster strikes?
