There is quite a bit of anecdotal evidence that CFLs can cause seizures, rashes and cancer.

I know some people who "hate the light" from CFLs. Since the color problems have been mostly solved, I think the subliminal flickering is what they object to.
Unfortunately, these problems are also shared with high performance T5 & T8 fluorescent tubes, which are very efficient and economical. Affordable and long lasting LED tube replacement bulbs are coming eventually, so I'd still recommend tube fixtures where appropriate.
