When George Washington started the tradition of swearing in on a bible, he probably couldn't have dreamed of electronic ink.

On Monday, Suzi LeVine became the first U.S. ambassador to be sworn in on a Kindle. LeVine, who is the American representative to Switzerland, took the oath over a digital copy of the U.S. Constitution while being sworn in by Vice President Joe Biden.

Geekwire has an excerpt from the ceremony, in which LeVine explains her decision to use the Kindle:

"As cool as a copy of the Constitution from the 18th century would have been, I wanted to use a copy that is from the 21st century and that reflects my passion for technology and my hope for the future," LeVine said.

Most importantly, she added, "it symbolizes for me the very best of our nation--especially around innovation, entrepreneurship, and the voice that each of us has in our democracy."

Also, LeVine admitted, the Kindle was what she had on hand.

As the Washington Postpoints out, this isn't the first time someone has used a digital device for swearing in. A group of New Jersey firefighters receiving promotions used an iPad in lieu of a paper bible last year, and a Long Island official took the oath on an iPad earlier this year.

But for a U.S. ambassador, LeVine's Kindle oath-taking is believed to be the first. It's as good a sign as any that we live in the future.
