I took it a step further and just use my home phone now. Not necessarily to escape any sort of addiction or privacy issues of feature phones (though the latter does cross my mind occasionally), but because when you retire a smartphone, the majority of your traffic is no longer data, but calls and SMS.
The codec used in wireline telephony is an order of magnitude better, so it starts to make a lot more sense; http://www50.zippyshare.com/v/sJG1ch4b/file.html
As for SMS, it's nothing Google Voice or any number of different services doesn't cover.
