and some of us Eco sensitive types use them instead of pilot lights on our stoves...

I have a pilot light on my oven, but they are turn off and i light my burners with matches. (i even have some of the illegal (in NY at any rate) strike anywhere matches) Lest you think cutting down trees to make match sticks is bad, i might point out, i cook so infrequently as to sometimes find cob webs on my stove. (thank god for toaster ovens and microwaves!)
