Personally I think that this is a good thing; what do other people think?

I'm astonished people are still using them. I haven't used incandescent bulbs for the past 13 years. And now the cost advantage of compact fluorescents over incandescents is compelling.
Electricity is currently around 10p per kwH
A 100W incandescent costs
£0.89, lasts for 1000 hours and costs 1p per hour
A 20W fluoresent costs
£5.35 and lasts 8000 hours, and costs 0.2p per hour
So the 'pay-back' time for the fluorescent is less than 600 hours - shorter than the lifetime of the incandescent.
(cost of incandescent for 600 hours = £0.89 + 600*£0.01 = £6.89
cost of fluorescent for 600 hours = £5.35 + 600*£0.002 = £6.55)
