Well put Joe...
I haven't had a landline in quite a bit neither and rely on VOIP today.
This doesn't mean that it's never gone down but for the few times it
ever has it has never worried me.
There's at least two cell phones in our house whenever the family is
home and I have neighbors within quick walking distance.
What worries me the most is a power outage longer than say 8 hours.
This is the typical battery time at most cell sites, telco remotes and
many telco CO's. Beyond those 8 hours, it's quite probable that the
site will go down and you'll have no cell or landline anyways. This is
purely geographically related as the larger centers have generators
attached - one could argue that portable generators would be used to
keep these battery sites up but in a large scale outage lasting more
than 8 hours I don't know a company out there that has enough portable
generators to keep ALL their sites up.
Have I seen my cell go down in a power outage? Yes
Have I seen my landline go down in a power outage when I had them? Yes

With GSM phones you don't even need a SIM in the phone to call 911
(and equivalent numbers in other regions).
I have two children at home, and I haven't had dial-tone on copper for
years. I don't lose any sleep over it; that's just one of a thousand
highly-improbable disasters that could happen, albeit one that
apparently enjoys better marketing than some.
If I *was* concerned, I think I'd buy a cheap GSM handset with no SIM
and leave it chained somewhere the kids could find, plugged in.
I seem to remember when I *did* have dial-tone from Bell Canada I'd
pick up the handset and get dead air a disturbing proportion of the
time. The idea that copper wire-line providers are the only ones who
can provide stable telephony doesn't ring true, for me. There's a
reason why the five nines don't include the last mile.
