I agree. Aditionally if the battery is the holdup the non plug in version could be avaliable shortly and be useful for making improvements on the eventual plug in hybrid version.I agree. GM should offer the Volt in 2 configurations. A lower cost non plug in version and a plug-in version with more battery capacity "Volt PI" version. Make the non plug in version upgradeable. Some of us (apartment dwellers etc.) will not be able to take advantage of the plug-in version but would like a more fuel efficient car. So why pay for the larger battery?
