I don't mean this to be a rehash of any of the other threads on the Time Capsule, or to reignite discussion of the circa-2009 issues with the Time Capsules. Anyway, I'm a new Mac convert (15" MBP), and I'd like to add a NAS & N network to my home (I'm currently running a G rounter for my Windows based machines. Is a Time Capsule the right tool for this, or should I get an Airport Extreme with an external hard drive? Does a Time Capsule work as an NAS, or is it really only a backup solution? (I was thinking I'd put my iTunes library there). Also, it seems that earlier TCs had major reliability issues; does that hold true for the new TCs, or were the issues addressed (power supply going out). Thanks!
