Sending a PDF i guess is cool but how pratical is that really, Faxing usually requires adding something to a document before sending thats why If they can make it fax a multi page doc from QuickOffice doc's or Docs to Go, Then this would be another app the iPhone should not be without. If you can't create and/or edit a doc then fax it out, then what good is sending the doc ... image taking of a doc makes it to small for the receiver to do anything with...... If they get this right - their orders would be flying off the shelves!
