I was quite surprised to come across few people today who on their web pages stated that they no longer use email and that they would not be needing it any more. Read more about them by following the links below.

Email is Evil - Das, Associate Professor of Finance, Santa Clara University

Also, note the interesting point(republished below) Don makes about the use of "email" versus "e-mail".

"Newly coined nonce words of English are often spelled with a hyphen, but the hyphen disappears when the words become widely used. For example, people used to write ``non-zero'' and ``soft-ware'' instead of ``nonzero'' and ``software''; the same trend has occurred for hundreds of other words. Thus it's high time for everybody to stop using the archaic spelling ``e-mail''. Think of how many keystrokes you will save in your lifetime if you stop now! The form ``email'' has been well established in England for several years, so I am amazed to see Americans being overly conservative in this regard. (Of course, ``email'' has been a familiar word in France, Germany, and the Netherlands much longer than in England --- but for an entirely different reason.)"
