The next ish of Reason magazine will be mailed out to 40,000 subscribers, with 40,000 custom covers, each bearing a satellite photo of the individual subscriber's neighborhood, with the subscriber's house circled.

But they make our lives unbelievably easier as well, in terms of commercial transactions, credit, you name it."
