Reality check on Pew Research

Read over this chart. It shows landline folks opinion (which is weighted to account for sampling considerations) contrasted with cellphone only folks (not weighted--about 10% of the population now, and then a column where Pew has "blended" and weighted the two. What is your take on whether the cellphone only folks opinions are different than the landline folks. And, when you look at the "blended" column, does it seem that factoring in the cellphoners makes little or no difference in the poll results? To me, it looks like adding them in does little to the landline only overall rating, but disguises the big differences in the cell only people's opinions. While only 10% at this time, they are younger and have other demographics. I'm going go back to my stats books and write more about this, but my first reaction is that pollsters are "wishing and hoping and praying" that giving up landlines isn't going to disrupt their business, but it looks like it will, to me.
