I hated CFL's until I became responsible for my own electric bill. ;) When I actually worked it out that we could have double the light for 25% of the cost (or something like that), we switched over every bulb in the house, except for the kitchen which has halogen track lighting. We're planning to update that to different fixtures sometime soon, so after that we'll be all CFL.
I particularly like the "daylight" CFL's. They often actually trick me into thinking sunlight is flowing into the room from a direction it has no right to be coming from.
