ok so I have a uestion about time capsul If I buy a time capsul can I use it just as an external hardeive? I am a photographer and I need to have my iMac and pc have acres to the same harddrive. And it needs to be over enthernet cable. I won't hve acres to Internet so I would only be using it for storage. So can I use 2 enthenet cables to connect the 2 computers to the device? Can I also connect to the drive via my MBA through the wireless?
