From a purely financial point of view, hybrids are generally not a good idea. Cost of the car itself is easily significantly higher than comparable models. The better gas mileage doesn't work in your favour unless you do a ton of city driving (b/c that's where they get the best mileage). A few years ago, the Vancouver Sun did a gas-powered vs hybrid comparison of multiple vehicles, and in only 1 out of 6 or 7 cases, the hybrid was cheaper to operate over a 5 or 6 years span.
From an environmental point of view, the manufacturing process of the nickel- or lithium-based batteries are not that environmentally friendly either, and battery disposal will be an issue 8 - 10 years down the road as well. (And we haven't taken battery replacement costs into account yet.)
The only situation where hybrids make sense are as taxis. They do a ton of city driving, and that's where the forte of hybrids lie. Regenerative braking dramatically reduce operation costs. But not many of us are taxi drivers.
