Fax was always awkward and weird. Resolution sucked and the paper handling was unreliable.

They were never common. They were mostly business tools, and consumers never wanted them. Sometimes you'd be required to send someone a fax, and you'd have to go to an office store. (And pay rather a lot; dollars per page.)

I hope you get to give one a try some day, for kicks, but the thrill will wear off fast.
