The Apple Time Capsule seemed like a great idea when it was unveiled about a decade ago. It was a Time Machine network backup target that also embedded a Wi-Fi gateway and ethernet sharing. Perfection, even if it was a little too expensive: It came with Apple technical support and warranty.
But it didn’t play out with the promise it had. An internal drive that you can’t physically remove or upgrade is a problem when it crashes or loses data, something that has happened to many Macworld readers. There’s no Disk Utility for Time Capsule. And if the Time Capsule hardware or the drive died, you could not swap that drive out without a lot of fuss.
