Anyone aware of a good personal organising program?

I’ve downloaded Sunbird and it seems OK, but I need something that has an auto start up. An address & phone number function would also be handy to put everything together in one place.

Something like Outlook but without the mailing and without being so goddamn slow and clunky. But auto-start is essential. I need it up because I’m forgetful!

Can anyone help me?

I kind of like C-Organizer.
