I bought this application just recently, and had an incredibly frustrating time with it to start with. It mixed up all my iCal categories (tasks and appointments), and it put all the email addresses in my address book in triplicate. Both of these problems I had to fix manually, which took hours.

I had hours of hair-pulling, and had I not backed up my iCal data at the beginning I would have had nothing left by the end-at one stage everything got deleted.

After this episode, however, things seem to be working ok. Category syncing with iCal is working well. If it gives me more grief with categories or email addresses, though, I think it will be back to the standard Palm software for me.
