I don't know about you guys, but I like my filament bulbs in the winter.
The lack of efficiency just helps heat the room I am in, so no big deal.
My summer bulbs are CFL's, soon to be LED's when the price comes down to
something a mere mortal can afford.

In the winter, this is probably true - what you lose on light
efficiency you save on heating. Then, the question becomes - per unit
of tangible heat energy, what costs less - the electricity to light
the bulb or the "other" source?

I am sure this can be calculated, but not by this guy! :-)

I have a big reason to not want the CFL's in the winter, radio noise.
DX sucks in the summer and the noise level goes up in the evenings when
everybody turns on their energy saving noise makers.

Imagine how much MORE efficient those lamps would be if they DIDN'T eminate
energy in totally useless RF ranges...
