It may look like just an AirPort Extreme base station — but it's not. Apple's Time Capsule is a new backup device that works with Mac OS X Leopard's Time Machine feature to automatically and wirelessly backup everything on your Mac. With super simple "just plug it in" set up, Time Capsule is available in 500GB ($300) and 1TB ($500) sizes. And, as you might guess, the device also functions as a full-featured Wi-Fi base station with with the latest 802.11n technology. Seriously, you now have absolutely no excuse to not be backing up.
