I'm getting my MBA and many of my profs do everything digitally from accepting research papers, to sending out syllabi to arranging meetings via e-mail.
One thing that I have learned, especially when giving a presentation is that if anything goes wrong, its your fault.
Powerpoint doesn't work? Its your fault. Didn't embed that YouTube video correctly? Its your fault. Your laptop can't talk to the projector? Its your fault. The Projector doesn't work? Its your fault.
If you aren't professional enough to have your research paper backed up on a thumbdrive, a second laptop for your group presentation, or even /gasp!/ a paper copy, ITS YOUR OWN DAMN FAULT.
Welcome to being a professional in the 21st century, where using technology is necessary, but knowing what to do when it fails is smart.
