One in Five Households Are Cellphone Only

According to a report by the Center for Disease Control (no, this has nothing to do with swine flu), one out of every five families has ditched landlines entirely for cellphones. I find that number a bit low, but what do I know? I'm deranged from swine flu because the CDC decided to tell me about telephone lines instead of top secret inoculation bunkers.

DISCUSSION

Considering broadband penetration in the US is only about 50% or so? I'm not surprised.
