Well, for those of my ever-so-many readers who have been following my PDA stuff, I believe that I have found a winner in the great PIM search. And the winner is.... Pocket Informant.
This program is really pretty awesome. Yes, it seems to have earned its many awards. Lupin's Diary, which was the other contender, suffered from being just a pretty face over the default calendar/task/notes database in Windows CE. Pocket Informant, though, takes the whole concept of organization to a new level, giving me exactly what Lupin's Diary was missing: links between tasks, calendar entries, notes and contacts. So, I can set up a task, such as moving all my stuff from Seattle, then link it to notes regarding my research on moving companies, then add a note for the company I chose and link it the original task. Then, when I finally get a date for pickup, I can create a calendar entry and link it to the task. This way, I can keep all of the information together.
Another outstanding feature is hierarchical tasks. The afore-mentioned “move my stuff from Seattle” task has several subtasks that need to be completed, so I can actually make child tasks that comprise the parent task.
As I've been reading the manual, it appears that the views in it are totally customizable. I've played a tiny bit with it, and it definitely does seem like I'll be able to come up with a bunch of custom views to show my business stuff and my personal stuff.
So, I'm still on the 14-day trial, only on the first week of it, but I am pretty sure this will be purchased.
