I am in the transition myself. I am just doing it by attrition. When a lamp goes it gets replaced by a CFL. I figure with the life of lamps the ones that really get used will all be gone in a few months.
We keep our house pretty dark so lighting is not a terribly big issue in the grand scheme of things. My work light in the kitchen has always been a flourecent. We also have reading lights by our chairs and by the bed but most of the lights are motion activated.
