The device, which supports 802.11n, automatically and wirelessly backs up everything on one or more Macs running Apple's latest release of Mac OS X Leopard.
“Bring Time Capsule home, plug it in, click a few buttons on your Macs and voila—all the Macs in your house are being backed up automatically, every hour of every day,” Jobs said. “With Time Capsule and Time Machine, all your irreplaceable photos, movies and documents are automatically protected and incredibly easy to retrieve if they are ever lost.”
