Personally,
You'll never get me to use any sort of CFL lamp in my house until I can be convinced that they are safe to use.
Reason I say that, is because, I have been to more than a few domestic fire calls related to these lamps and have had a couple of bad experiences myself with the things overheating in use, one even caught fire and badly scorched the ceiling around it.

I use fluorescent fittings in my workshop (twin tube 58W units) and I've never had a problem with them, so why are these CFL's so prone to early failure?
And a catastrophic failure at that.
Could it be sub-standard materials or manufacturing processes?
