a 2TB 15mm 2.5" WD hard drive costs $160 to $180. Apple is only charging $100 more. Kudos!
a 3TB mobile drive doesn't even exist as far as I know. (please correct me if I'm wrong, since I'm looking for one of these.) So I can't wait for you guys to tear down a 3TB AP Time Capsule. Could it be TWO 1.5TB drives in there? Regardless $200 more for this is very reasonable.
Apple used to charge $200 more for the $70 1TB drive, which was a major rip off, since I could just get any external USB 2TB drive for $100 and get the same functionality of time capsule.
