Mobility isn't so easy

US Spends more on mobiles than land lines - L'Inq

I don't find this report surprising since I have never had a land line attached to me personally. It's been mobile all the way for me. But I do wonder what consequences this will have for corporations who rely on telemarketing and bill collections. When you separate the phone from the physical location doesn't that start to present a problem for those looking to collect on a late credit card payment?
