I have one, but for different reasons - most notably VOIP can't guarantee you 911 service in the event of a power outage (e.g. earthquake that wipes out a lot of the infrastructure). Ditto mobile/cell phones. One of the first major failures in Katrina was the cell phone network - got seriously overloaded and people couldn't make calls. Those are my reasons more than SSNs and stuff.

Cellular networks are encrypted - for someone to eavesdrop on your digital cell phone conversation would have to mean they REALLY wanted you bad. This does not apply to old analog cellular networks - if you "roam", often you're using analog. Something to consider.

Cordless house phones are radios. Some are encrypted, some are not. A few years back I listened to one of my neighbors spill her guts (name, ssn, credit card numbers, etc.) over a cordless phone - I was able to hit the frequency with my bearcat scanner.

If you always treat a wireless device as a radio, you'll be safe. Using the internet with 128-bit encryption is probably safer than voice in most cases regardless though.
