If you don't remember about the Time Capsule, then let me refresh your memory a little... Basically, we're talking about a 802.11n AirPort Extreme router that has a built in server-grade hard drive. This device works with Apple's Time Machine software to help you perform automatic wireless backups of one or multiple Macs running Mac OS X Leopard.
Currently, on Apple's site you can find the 500GB Time Capsule, priced at $299, as well as a 1TB setup, sold for $499. To find out more about the device and, maybe, order your own, feel free to visit the official product page, here.
