A lot of it is simply people not knowing how good CFLs are these days and taking the cheap purchase over the long-term savings. I prefer the light from my CFL bulbs over the few incandescents still left in the house.
What happens when LED lights hit the market?
Socket-fitting ones are on the market, but they're not very good and too expensive. The environuts will probably want to ban CFLs when LEDs mature. One of my favorite upcoming battles is when the global warming wackos ("Mandate CFL!") face off against the pollution wackos ("Ban CFL because it has mercury!").
This is of course not the solution. Wal-Mart is going one of the correct routes by simply raising the visibility of CFLs in its stores. Let the informed market decide.
I have tried the more expesive "same as" compact florecents.
They are not the "same as" and are not as good as incandecents when it comes to natural lighting.
Then there is that ubiquitous "do not use with dimmers" deal breaker.
Good for the garage, not for the living room.
But that is why we have the free market, eventually they will get it to the point where it is cheeper than and of sufficent consumer wallet value to not notice the difference.
But not yet
