Hi everyone, Questions on Time Capsule...basically for $200-250 or so I am finding 2TB hardrives since prices have been driven up. Just got a new iMac, so I need a backup. For $300 I can get a Time Capsule and be wireless. For wireless storage and backup, does it need to be connected to my Airport Extreme? (which is in another room, and already has an HDD connected for media storage for my whole family). Can it just sit on my desk plugged into the wall, nothing else. Can it be partitioned for backups and storage, all wirelessly? With the USB port can it be expanded to larger size with another external drive, and still backup as if it was one drive? (I think the term I'm looking for is slave drive, but I don't know). Can it double as a wireless signal extender for the already existing network set up in my home? (while still acting as storage and backup available to me, but not my brother or father on their macs). I hope some of you have some answers. I couldn't find too much on Apple page that spelt it out clear for me. Thanks All!!!
