I have been trying for probably a year now to find the, for me, perfect PIM. It has to include email, calendar, to do list, and some type of memo option. A big concern has been reminders, be they by email or application pop up, for both calendar events and to do list items. The Linux KDE package, Kontact, appears to do the trick.
Many people use the calendar for all appointments/tasks that require reminders. I am however of a mind in which I deal with deadline based reminders and goal (not time sensitive) reminders. The difference may be subtle but to me it is significant. Hence I require a PIM with which I can configure events and tasks using an automated reminder system.
It was very easy to import all my mail from my Linux Evolution client. Two or three steps pulled in all my folders. Contacts, exported as Vcards from Evolution, were easily imported into KAddressbook and integrated into Kontact.
I had some issues getting KMail to recognize my address book after importing it to KAddressbook. After multiple deletions and recreations of the address book, I got it to work. Unfortunately, I am not sure what the problem was or why the fix worked.
Nonetheless, it seems to be working as I would like it to so I’ll keep testing it out and hopefully adopt it as my “new” standard.
