Putting mutually desired programs on both does use up some more space, but it solves many of the conflicting scenarios. Remember that once the first one of you watches a program, it gets deleted from that particular box so it's not as if it's taking up double the space forever. And if you watch it together, deleting it frees up twice the space . If you put the commonly wanted shows on just one box, you're back to the original problem again. Similarly, having two cars instead of one will cost you more in gas and insurance (in addition to the obvious cost of the car itself), but if the scheduling and locations of your workplaces and other activities are quite disparate, the extra car goes a long way in reducing the location and timing conflicts.
