Sharp's new UX-B800SE Broadband Fax does the usual boring squelchy phone thing, oh sure, but it also has an Ethernet connection allowing you to send PDF or TIFF scans (two-sided, if you prefer) of your documents via email, as well as receive analog faxes and email them to you if you're like the tethered office drones of yesteryear, waiting around all morning for so-and-so's fax.
