If I'm not mistaken, the new CFL's are a completely different technology with a different compound than the straight tubes. Never was warned about breaking a florescent tub.
Some outlets are starting to recycle (I think Lowes and Home Depot, maybe Walmart). Just be careful transporting them to recycle.
I've got CFLs - some inside my house encased in a flood light and some outside that stay on all night. I hate to put them into the landfill, so I'll figure out how to recycle when needed.
