It is if you close your Notebook 10 seconds after adding a new entry in Calendar.
Exactly! It's all very well saying you can do a quick manual sync before you close it but what if you forget? One of the reasons I was very interested in this technology is because I have a lot of appointments for my son who was born premature, and so my wife will often set them up then let me know at work so I can add it to my calendar at work. With MobileMe she should be able to go into my calendar at home and it all syncs instantly so I can see whatever she has added by logging into me.com from work... I can't expect to have to show my wife how to sync first before she closes the laptop and expect her to remember to do this every time! I do not see how difficult it is to update the iSync on the Mac so that if there is an event change or update in iCal it will run an immediate sync and the same for Address book, seems like a pretty simple solution to me
