.....it got me wondering how important is the ability to use a computer to function in today's society let alone for communications use in an emergency.
Dude, are you serious? In today's world it is extremely difficult to function at a high level without access to a cumputer. Any one who says otherwise is kidding themselves. Also note that anyone who reads this thread, let alone responds, is using a computer. And I find smart phones and texting to be extremely useful.
Change happens. Deal with it.
