There were plenty of areas that already required 10 digit dialing prior to this due to past area code overlay changes. This list adds a bunch more areas. I have to wonder how many places are left that still allow 7 digit dialing? On a cell phone, I've legitimately never even tried to use 7 digit dialing, as it has always seemed too risky, as it might do the wrong thing if connected to an unexpected cell tower near an area code boundary.
