It's cool how hybrids are making their way into existing models (e.g. Civic, Accord, Escape, RX).
Sure, the Prius and Insight are the hybrids, but they scream "look at me! I drive a hybrid!". A lot of people don't care for that.
In a few years, Toyota and Honda will have hybrid options on most of their lineup. Good stuff.
As for whether or not a hybrid is "worth" it...if people pay for it, then it obviously is.
Do you help the environment? Yes. Do you save money in the long run? Maybe. Do people already pay A LOT of cash for the status of owning something that other people don't? You bet.
I'm sure there are a lot of hybrid buyers out there that buy the vehicle simply for the satisfaction of owning something that's above the competition. Just as a lot of people buy Mercs, BMWs, Lexus', etc. just for the badge.
