Hi,
Our school (NYU) has just introduced DVD's this year. I think BU introduced it last year.
I personally hate studying off a laptop. It strains the eyes, it is difficult to navigate, it is tough to take notes in the text (despite the new built in feature to type in notes).
There are definitely some advantages, like you dont have to carry a lot of textbooks around. It is probably better just for a research tool, just to look things up quickly. But to learn off of it is just horrible.
