I use it, despite owning the full version of Acrobat. I use it mostly to insert signatures into documents and sometimes to fill out forms that don't have fields already (i.e. faxes I receive via an efax service). It's quick to create text fields. Acrobat is a little clunky now for creating just one or two text fields.
