I don't get excited about it. When we have family dinners we just ignore any cell phones or even our house phone while we eat. The children are always included in the discussions over food, and thoroughly join in. I find this to be one of the finer things of family get to gathers. I love to hear the youngsters point of view on all things permissible. They don't even think about answering a phone.
OTOH, my Wife has her office on the third floor of our home, and I have my man cave on the bottom floor where I can walk right out to the pool and lake. There is a reason for that. Neither one of us wants the other to mess with their computer, and whenever there is a problem, we both think we know better. See, it's best for a happy marriage.
Here's where we use the modern technology. If I desire to take her out to lunch I either call her on her business line, or I sometimes e-mail her. That's much easier than yelling up, or climbing two flights of stairs. Works good for us.
Technology is not always bad. :D
