Mozilla Sunbird

I'm looking for a way to synchronize my calendar and todo list at home, at work and in my old Palm IIIxe.

Actually I use Outlook for my work calendar, Palm desktop for my personnal calendar and todo list (both for work and home todos).
But it's becomming a bit messy...
I just dicovered that Mozilla foundation is creating a new project from Mozilla Suite call: Mozilla Sunbird. Some screenshots here.

It's not officially release but It has everything I need (and even more):

• Import/Export in vCalendar format (outlook) and iCalendar format
• Export to a local file or remote file
• Subscribing to a remote file (of someone else calendar for exemple)
• Export to a WebDAV server (such as Slide for example)
• And many other features...
  

So my problem now is that:

• Palm desktop is free and can be synchronise with my palm
• Sunbird is free and has a good look and feel
• Outlook is used everywhere but it's not free.
  

I think I'll just give it a try...
