The built-in PDA functions on the Palm should be synching easily with Outlook. A few years ago I migrated from Palm to Pocket PC, but even back then, the Palm "talked" to Outlook on my desktop easily. Now, after the migration, I still do most of my task management and project management in Outlook on the desktop, and when I synch my Pocket PC to the desktop, Outlook just communicates the tasks and calendar items to the PDA software on the Pocket PC. That didn't change when, two years ago, I installed the Add-On to Outlook. I find that the Add-In makes implementation of GTD much easier, and Outlook still "talks" OK to my Pocket PC. Keep in mind that the Add-In is for Outlook, and not for the PDA software that is installed on your Palm. You might not see all of the features on the PDA that you see in the desktop, but it's still a lot better than operating without the Add-In. If you're having trouble with the Add-In on your Treo, there is one thing that you might try. (It helped me resolve several difficulties.) In Outlook on your desktop, click on Tools/Options, then click on the "Getting Things Done" tab. The "Update Task Actions" button at the bottom helped me to resolve the problem that I was experiencing with categories on my desktop not matching categories on my Pocket PC. It's still not a perfect marriage (and after 37 years of married life, I'm not sure that there is such a thing) but my Pocket PC and my desktop now seem to play well together. Also, the new (free) update to the Add-In is due out this month, and is supposed to address many issues.
