I am quite frustrated with the state of palm syncing on Mac OSX. See my post here about the well timed collapse of my syncing setup. I currently use my treo to access my PIM information more than my laptop (which is partly due to not having a good way to sync)

Heres is a list of pains inflicted on me by the combination of my Treo 650, Missing Sync, and Mac OSX:

1) My notes have been over-written by older versions of my notes from my computer several times
2) My tasks where re-arranged and assigned new categories.
3) With versamail trying to sync to an exchange server I've lost my calendar several times.

I've tried the following methods of syncing;

1) Missing Sync to the Mac Applications
2) Versamail with Exchange
3) Missing Sync to Entourage

Since I made the switch to Mac, this is the first time I can say it was much easier to complete a task on my PC. Yes, I did have a hard time setting up my PC to sync, but it didnt take this long, and I never lost any data.

Even more frustrating than syncing with Missing Sync to the Mac applications was trying to sync to Entourage. After some research I found:

Mickey Stevens Office & Mac Resources. I had been to the Microsoft site several times, and failed to find anything this "useful".

Below is a list of common issues encountered with Palm synchronization:

NOTE: At the moment, Palm devices with Organizer Plus include Z22, Zire 31, Zire 72, Treo 650, Tungsten E, Tungsten E2, Tungsten T3, Tungsten T5. TX, and LifeDrive.

Data loss when synchronizing with Organizer Plus applications
Some of the new Palm devices have "Organizer Plus" applications. Unlike previous Palm devices, these new Palm devices include Calendar, Contacts, Memos, and Tasks. They also have new features that are not recognized by the Handheld Synchronization conduit. This problem is described in detail at the Microsoft Knowledge Base. Unfortunately, there is no workaround at the moment.

I found this post from 2004, amongst others that talked about people loosing data or having data shifted around because the entourage conduit didn't know what to do with the new data fields.

Now, I havn't had the time to do much more research, but the words "Data Loss" concern me greatly, and I thought were at a point in PIM history that was beyond these kind of troubles. I was validated in not being the only one to think this. My boss at work also had the same reaction as he started to look for a more powerful smartphone to manage his personal info.
