The news that Apple is discontinuing the AirPort line, although expected, is a bitter pill to swallow for many Mac enthusiasts that love the no-nonsense, easy to administer backup and recovery features on the Time Capsule series. Even though the Time Capsule will be no more, you can still use Time Machine for your backup and recovery purposes in your post-AirPort world.
I imagine this is a question a lot of people have since Apple announced it would discontinue the AirPort product line. The good news is, the Time Machine technology will work, without a Time Capsule.
