My android phone also uses USB for charging and data transfer, so it wouldn't be hard to hang it off the back of a PC, place it out of sight, and never worry about the battery running down (my phone doesn't show up to the computer's OS until you tell the phone you want to connect).

1) Younger people are still more used to digesting content directly from an electronic screen, so they don't feel a need to convert it to dead-tree form for a more "natural" medium.
2) Younger people are probably more likely to trust that the email will still be there*, and they are able to use search tools to find it, whereas older generations may feel (even subconsciously) that if they don't print it out and put it in their hard-copy filing system, they may not have access to it again. I think the only reason my mother has cut down on her printing of every "interesting" email is that she has spammed herself into oblivion with mailing lists & such, to the point that printing everything would be cost prohibitive.
*Assuming there's not a ridiculous "all email will be deleted within 90 days, and no archiving or auto-forwarding allowed" policy, like with my employer.
