It's not like they'll be getting rid of voice 911. It's just an option 
you can use if you find it more convenient in a particular circumstance.

Many of today's kids and teenagers are very proficient at texting, so 
when they grow up they're likely to find this a very useful feature. I 
still use a flipphone with only a numeric keypad, it takes me forever to 
type even a short message.

One thing we've done in the past is to plant a PVC conduit about 18-24" 
under the ground. Fish enough wire for your needs but drop a few strings 
in there to pull cable through for additional needs.
