As I understand it, because it's not stored in liquid form, the compressing & refilling routine is a much slower affair. I don't know about other areas, but in Sydney, there are next to zero outlets.
Having said that, the idea of re-fueling at home, overnight whilst the car in in the garage, at cents per litre is very appealing.

Other downsides are bigger/heavier storage cylinders required and because CNG is a gas, as the cylinder empties, the pressure drops (hence performance). There are probably engineering solutions, but at a cost.
