I have carpet because it doubles as a guest room. But, we're eventually yanking out ALL of it and replacing it with either wood or laminate. Much easier and safer(no hidden pins etc). And carpet is soooo bad if you suffer from allergies or asthma. No matter how clean of a person you are, have you seen the dirty water come out of a steam cleaner?? YUCK. All I know is I'll never have carpet again! Luckily, I live in CA so I don't have to worry about the floors being too cold etc. But, if I lived elsewhere I'd go with heated tile etc. and still lose the carpet.
