The business model of the company discussed in the article has them owning the battery and the consumer leasing it, so they take responsibility for it. It sounds like they are planning an exchange system similar to what is available with 20 LB propane tanks, augmented by the ability to recharge it at home and work.

I think the hybrid will be the only viable electric model for long distance driving for some time. Unfortunately, dealers who could not get enough of them a year ago are having a hard time unloading them today. It seems consumers are not willing to pay the premium price for a hybrid now that gas is under two bucks.
Some manufacturers are even offering rebates on their hybrids these days. There are some great deals out there for the people who still have a job and aren't afraid they are going to lose it. I hear both of them are going to buy a Prius.
