I just bought a Nissan Leaf. The decision had nothing to do with the environment, I did it for the convenience of not having to go to the gas station or get oil changes any more. After about a month, I am in love with the car. It's comfortable, amazingly quiet, and surprisingly powerful. The acceleration is better than any other car that I've driven, it's super responsive. It was also very inexpensive. I think most consumers are like me and will make the EV decision based on economics rather than environmental concerns.
