No email for 20% of US

According to this article:

Roughly one-fifth of all U.S. households are disconnected from the Internet and have never used e-mail, according to research firm Parks Associates.

...

Age and education are factors in this divide, Park found. One-half of those who have never used e-mail are over 65, and 56 percent had no schooling beyond high school.

That's a lot... buy computers people!
