If we're allowed to add something that's part of using a computer, I would say email. Having been self employed for 11 years, if you'd said to me then that I would manage to have a client in Dubai (UAE) and work at such a long distance electronically, I wouldn't have thought it possible - but it was, and is!
I certainly find I print a lot less work for clients now - they just want it emailed to them for them to manipulate/add to other documents etc
