Mobil me
I have been using mobilme for 2 years. It works fine when set up. One thing you might do is make sure that you are not using itunes to sync calendars or imail. Also do not use itunes to sync any data that mobil me can do. Go to your settings on your mac and select mobil me, Then select the sync tab and select what you want mobil me to sync to your ipad. then go to the advanced button and select it. Select your computer and then select reset sync data then set the arrow to point to your computer. This will then send anything from mobil me to your computer that you enter from the ipad, and you ipad pointing to your computer.
