In some places, fax hasn't gone out of style at all. "Faxing, especially, is a network technology… the more people who use it, the more valuable it becomes," Coopersmith says. In Japan, where it seems the majority of people still rely on faxing for all manner of communication, it's very valuable. While it's partly a matter of habit, the fax machine offers some pretty appealing services, like a way to communicate even when the internet's down. And faxes aren't just confined to the office, either. They're in the home, in the form of a 2-in-1 machine, with both fax and a landline phone.
