If I get past the Hg issue, I will put FL in some places but not in others.
That is, unless the address the light quality issue that I am concerned
about. Areas where I will be working for more than 20 minutes at a time
will have incandescent/halogen lights.

If they come up with suitable replacements, I'm fine with using them.
Maybe the Hg issue won't be much of one. I'm considering the fact that
so far I have never broken an FL light outside of some intentional acts
when I was a teenager. The spiral of CFLs seems to be a stronger glass
than the long tubes, as well.
FYI, I also intend to avoid the E26 screw base in as many places as I can.

We have a broad spectrum of people out there that range from wanting to have
the lowest price at everyone else's expense, to those willing to pay triple
and more to ensure they impact no one else. It will be interesting to watch.
I say "tax it". If you don't want certain things done and can show a good
cause why (it impacts others in some way), then tax it. That comes down to
electrical usage. Raise the tax on the _generation_
of electrical power that
is made from coal. Or just tax the measured pollution produced (leaves open
the possibility of developing better cleaning processes). I'm not concerned
with the banning of A19/E26 white incandescent bulbs because there are plenty
of alternatives. The yellow insect bulbs can be used for reptile warming.
I can go with new fixtures that use bi-pin halogens, especially at low voltage.
If I were caught under the silliness of California's law that requires a
certain amount of lighting be the high efficacy type, and focuses on the
kitchen, where I need good quality task lighting the most (and generally
for no more than an hour or two a day, except on 2 or 3 holidays a year),
then you will see HPS lights (unused) dominating the kitchen while I still
used localized halogen task lighting there.
