Unfortunately, it has been a long time since I switched to Leopard and NUTC 5.3, so I cannot remember if there was any particular problem I encountered with syncing to my Treo 700p. However, it does work and I have not really encountered any trouble. The only thing that kinda comes to mind is that after upgrading everything, I needed to download and reinstall the Palm Desktop to get the latest version of the Hot Sync Manager.

That said, I have been running this way for for quite a while now with little or no trouble.

Hope this helps to calm any fears.
