Two questions: 1. Does anyone know where I might find an extended battery for the UX50? 2. Is it necessary to uninstall the Palm software to get rid of Hot Synch if one would want to also synch an HP Ipaq using Active Synch? Is there a conflict with both using Outlook for contacts? HP instructions say to uninstall Hot Synch when changing to the HP Ipaq software with Active Synch.
