Yes, the PC interface cable and (slow) backup and address entry software comes with the unit!The To Do list nicely sorts entries by alphanumeric priority, so you can organize by categories like B for Buy or M for Movies, as well as use priority levels 1 thru 9.Fits nicely in your pocket, with a keyboard which is quite usable for typical short entries.The calendar's monthly display shows morning and afternoon appointments at a glance.I'm completing software to speed up the slow backup and to allow importing and exporting entries. Email me if you would like to test and comment on the utility.
