Recharge time is more important than range. When they get the time to charge the same as the time to fill a 20 gallon tank then call me.
For me its all about price. Get it as low as a regular car, and I am in. Assuming decent range (200 miles). See, I dont need super range or super fast chargine, thats what my OTHER car (gas guzzlin truck) will be for. The vast majority of my driving is less than 100 miles per day, and an overnight recharge does the trick. So I say bring em on.
