If you count the one in the microwave, just that one! 
Longest burning ones in service household wise, (outside and indoor nightlights), are LED
Main house lighting are all CFL! 

AngryHorse, what about the ones in the oven? 

In my (family's) home there is at least one incandescent lamp in use for general lighting, and it's used almost every day. And of course we have one incandescent lamp in the oven and one in the microwave oven. We have also plenty of halogens in daily use, mostly 12V 20W ones. I have replaced some incandescent and halogen bulbs to LED ones this year because they have burned off or I've wanted to "update" the light color to 4000K because it fits better to some rooms of our house.
