Looking at the reviews on Apple.com for Time Capsule, it looks like Apple really stinks at making back-up hard drives. What would be a good Alternative? 1. Being able to use Airport to back up and not have to plug it in to the iMac would be a *big* plus. 2. It doesn't have to have automatic back-ups. Just backing up when I make it back-up would be fine. 3. 1 TB Hard Drive. So far I've looked at G-Tech G-Drive Q 1TB, Hitachi Deskstar 7K1000 Hard Drive - 1TB, and the LaCie 1TB d2 Quadra Hard Disk, though I don't see 'Airport' in the descriptions/Features.
