Are you sure you have realistically evaluated this activity as quality with your wife AND children? Just be sure everyone's on board with this!
Note: this is opposed to the original (snarky) response which occurred to me, which was that probably a recliner would not afford significant relaxtion in comparison to a quart of whiskey!
Oh, certainly I wouldn't call this quality time with my wife and children! It's more along the lines of "better a little poor quality time than no time at all". I do also of course spend time *without* the computer, but I prefer to be with my family as much as possible. This is for the times when the alternative is not seeing them at all.
We have a equal opportunity Calculus class -- it's fully integrated.
