SyncML is supposed to be a powerful standard with even push mail capabilities but seeing how many hoops one has to go through I am skeptical of its value.

The ideal scenario would be a built in SyncML client and a SyncML server (preferably free) that is directly connected to Google Calendar/Outlook. That way you just insert the SyncML server id in the inbuilt client and your are done syncing with Google and Outlook.

Those who are thinking of attempting this, I don't think many will - this is a one off case and too much trouble honestly - it will be good idea to back up your contacts in Windows address book or something. That way you can experiment in peace to set up the sync properly.
