The National Center for Health Statistics updated its estimates on the size of the population without landline telephones. The data is was collected from July - December 2006, which means that the wireless only population is probably higher by now. The full study is fascinating and located here.
The age group with the highest wireless only penetration is 25-29 year olds, at 30%. I'm one of them.
I don't know how this impacts traditional polling techniques, but I am curious.
