Don't wait for a plug-in hybrid?

Why you should just buy one of today's hybrids

There are many out there very interested in plug-in hybrid vehicles. Some won't buy another vehicle until they can buy a plug-in hybrid. And, while I understand this view, I say buy one of today's hybrids.

Already, hybrid cars such as the Toyota Prius can be converted into plug-in hybrids, but such conversions aren't cheap. The important thing is that it's technologically feasible. So, for now, just leave your hybrid as is, but in the future you can replace your NiMH pack with a lithium pack. Or, add a removable pack or two to your trunk to extend electric range and fuel economy.

Ultimately, today's hybrid cars can be a long term investment, or at least a long term hedge against high energy costs. And, if the battery pack does clonk out after the warranty is up, you'll be able to replace it with a cheaper and more efficient battery anyway.
