Tested out Intellisync a year ago but got fed up with the lousy Puma tech support and slow sync speed. I found a product called PortaMail while searching the Novell site and I haven't looked back since..that was in May 2002. It does a great job of syncing mail, tasks, reminders, calendar, and addressbook, all pretty fast. They have very responsive tech support the a forum interface. You can find more info at

In Canada the price for PortaMail was pretty well the same as Intellisync. I work in Tech support for the Provincial government and this product solved a lot of problems for me. Now if I could just get the Palm users to embrace the Pocket PC world but logic has no place in that argument
