rhkuo, I wote for a wikipage for this! I will gladly help you maintain it since im a heavy pim user on the n800.. and im also desperate for good and better pim software. Right now Im using GPE calendar syncing it with my google calender with erming.. that give me basic calendar functionality tough I realy think the gui in GPE calendar is crap. For tasks I use gTodo, its good enough but thats barely.
