Email, a Legally Binding Contract?

slashrot writes "Boston.com has a story on a dispute between a home buyer and seller in which they agreed on terms in a series of email messages. Superior court judge Ernest B. Murphy decided that even though these messages only contain typewritten names instead of signatures, they still constitute a binding contract. It's said to be a first in Massachusetts." The particulary look to me like a home seller trying to weasel out of a deal, but the ramifications of the decision are substantial. This is really worth a read.
