I had a old Palm PDA and then a Treo and LOVED their desktop calendar software synced with the device. When my Treo died and I switched to a Blackberry I tried Google Calendar (actually have tried it a few times) and have just not been able to make it work. I've been back to paper and pencil for a while now. Like PPs, I like the ability to have my past data archived. I had years of calendars archived and backed up with the Palm desktop software. I don't have MS Outlook, but I think that might be a good solution and have considered it.
