In 2012, it seems to me that hybrids have rounded the bend, and crossed a very significant threshold. In some cases, it appears that the purchase of a hybrid is, in addition to environmentally considerate, cost beneficial.
A new technology like hybrids had a lot going against it in the early going. Purchase prices were high since production quantities were low and R&D costs were significant. Also, new technologies are less reliable than tried and true ones; they have not been through the iterations that come through multiple generations of development.
