More people use email than any other part of the Internet.
Unlike other parts of the Internet that are only beginning to change legal practice, email already has and will continue to do so. Email is the killer application, the paradigm shift, that impacts lawyers on a daily basis. Anytime information has to be put on paper, whether it be for a snail mail letter, a fax, a brief or a report, a bottleneck is created. The information on that page can no longer be easily manipulated and forwarded by the recipient. A fax had to be delivered, read, a reply composed and typed, a cover letter prepared, a number dialed and if not busy at least two pages sent.
