that will be used as an iTunes database? I'm debating a laptop but I don't want to have to have it connected whenever I need to backup or if I want to watch something on my Apple TV. My setup right now is my iMac connected to two separate external hard drives one as a backup and the other for iTunes. If I did go the laptop route with Time Capsule, will I get the EXACT same results, just wireless? And what happens if take my laptop to work one day and I leave my wifi while backing up unintentially? Could that cause problems?
