Does anyone use the PIM, !ntellect (or Time & Chaos) and sync it to their 800W?

Coming from Palm I could sync contacts, calendar, tasks, and notes. Now with the 800W it seems I can only sync contacts, calendar, and tasks. I use Companionlink to make the sync--as Activesync won't sync directly to !ntellect.

Is Outlook the only safe PC PIM to sync seamlessly, and fully, with an 800W?
