If they are more comfortable with computers, then a good teacher will use computers. When printing first replaced manuscripts people made the same outcry. The first printed books were available to few, full of errors and often illegally obtained copies. That properly designed computer screens are damaging to the eyesight is as fallacious as blindness linked to reading by dim candlelight. I don't see why students would be less likely to make notes from a computer than a printed document.
Cliff notes are just as easy to cop as an online essay.
The key is to get students excited. It excites me that I can look up the OED almost everything Virginia Woolf wrote, and a ton of essays on ED all from my desk, right now when the desire strikes me, not having to march to the library or the really bad bookstores in my town. I'm sure that that's the excitement that strikes students too. Differences in pagination is a technical problem you can work out, difeerences in edition a starting point for discussion of variation in publication. Remember we are there to instill in students a love of the material, not their corporeal forms.
