Yesterday I downloaded iCal for Jaguar (Mac OS X 10.2) and started to use it instead of MS Entourage. My needs are pretty simple (I'm using my paper calendar and my Nokia mobile for keeping appointments), basically just to remind me to take breaks from the Mac every once in a while (lunch, coffee break etc.). This seems to work ok. Some features of iCal are a bit awkward, and some things don't quite work smoothly, but probably this product will improve in the next versions. Anyway, this is a good start in the right direction.
