Hey faxers, don't get too excited, but Panasonic will be releasing a paperless fax machine before the end of January. The bad news? For the moment, it's Japan-only. I'm actually quite surprised that it's taken the human race this long to develop a machine that sends faxes without actually having to feed in paper.
To send, you can type messages mobile-phone-keypad-style on the big built-in buttons, or alternatively you can send Word docs, as well as docs saved in 'other formats'. Presumably PDF will be among them. Fax messages can be read on the device's screen and, sadly, printed out if you absolutely have to.
