Hi, could you please help me understanding how the sync and backup functionality works between my iPad 2 and my MacBook ? I have bought several Apps from the app store mainly directly from the iPad 2. In particular I have AVPlayerHD with some heavy related videos. The problem is that after the latest sync with iTunes the free space on the internal HD of the MacBook is gone down dramatically and the 250 GB HD is almost full !! Here are my questions: - Can I maintain the Apps ONLY on the iPad without a second copy on the MacBook ? If I uncheck the option "Sync Apps" in iTunes am I deleting the apps also from the iPad device ? - I suppose that my purchases are registered in the AppStore and I can always download the app again ? - How can I configure the backup options of the iPad when is attached via USB to the MacBook ? - Where is the backup stored on the MacBook ? I know is a lot but hope someone can help... thanks.
