Personally I find that they last a heck of a lot longer than incandescent bulbs do.

Thats really not an apt comparison necessarily. If the bulbs are very expensive and the price of electricity is much less your equations won't work.
Also no one has mentioned power quality. The switching of the power supply in the CFL may cause harmonic issues and wreck havoc on the power grid due to poor power factors
