I really did like this product until an update caused a total failure in the ability to sync to Address Book or iCal. Tech support has been nothing short of amazing in trying to solve this issue but we've both spent hours on this and I do have a life. I gave up on the product and now I'm back to Address Book and iCal (and without any sync issues, CardScan). Its clear to me that this is a Daylite problem as I was able to sync to competing products and even the beta of Now X which I might migrate to when its released. IF this company can fix the sync issues, I might go back but at this point, its just too much a headache.
