Transfer to PDA
I reckon it took me four plus years to completely move from DayTimer to PDA.
At first, I concentrated on using my PDA for Contacts and ToDo lists as well as spreadsheets, databases and text documents and the DayTimer for monthly/weekly/daily schedules.. As time went by I saw ways of integrating and cross-referencing the Agenda/Datebook with these other applications which made a more compelling case for completing the transfer. It was made easier when I was given my own personal laptop at work which I can take everwhere and use to keep fuller details of all of these.
I still miss doodling, so I carry around a spiral shorthand notepad with me for meeting notes (if I'm secretary I take minutes directly onto my palm using a fold-out keyboard). At work I use A4 lined pads - what you call 'legal pads' and process through my in-tray.
On the idea of a recurring tickler I recently came across the idea of using recurring to-dos from the Outlook end.
In Outlook you set up a recurring task which could be weekly/monthly etc, which even offers a delay before displaying the next occurrence. If you sync with a Palm regularly, it pops up there in due course because Outlook takes care of the recurence.
