Hi All! SO I FINALLY decided to replace my trusty custom built PC with an Apple desktop -- ordered a refurbished 27" i7 iMac w/1TB SSD. (I didn't see the point in waiting for the retina version...although my focus is on photo editing, I figure it will be at least a decade before 4K displays become truly common...by then I'll have a whole new system). MY CURRENT SETUP consists of a desktop PC, Airport Extreme router with a 1TB SATA drive hanging off it for backup and file sharing, as well as a USB printer. I'm also using a mac mini as a media centre and my son uses an older Macbook. I'M THINKING of adding a 2TB USB 3.0 to the iMac for photo storage and replacing the Airport Extreme with 3TB Airport Time Capsule dedicated to Time Machine, and continue to use my 1TB SATA drive as a file share. Couple of questions.... Is it worth cost of replacing my Airport Extreme with the Time Capsule, it being noted I could just tack on a USB 2.0 drive to the AE and be done with it? Is Time Machine a reliable/effective backup choice, or am I just better to manually copy files to an external drive like I've always done? Comments or suggestions of any sort welcome. Thanks!
