I need to get an external hard drive cuz the space on my Air is nearly used up. Im looking to get a 1tb drive. Should I get Time Capsule or get a random drive? I have an Archos 7 tablet so ill need to store all of my movies on it. Would Time Capsule allow me to do this or does it only store things from Apple software ie iTunes etc? Also, if the shoe is on the other foot, if I were to get a random 1tb drive could I drag all my itunes music onto that as well?
