WHY COMPLEX IS CO-SIGNING IT: Because when your computer crashes, and it will crash, it's going to hurt bad when your realize you just lost your term papers as well as your music, video and photo collections that you've been compiling for however many months or years. Western Digital's My Passport Essential SE will help you sidestep such a disaster. Their newest mobile hard drive comes in 750 GB and 1 TB (terabyte) capacities wrapped in a sleek package that checks in at less than half a pound in weight, less than an inch thick and only 5 inches wide. Thanks to a USB 2.0 connection you get crazy fast transfer speeds (480 Mb/s) and the ability to power the drive solely with the USB connection, making it that much easier to just toss in your backpack and go. We recommend going for the gusto with the 1TB—it may sound like too much space, but that's like saying Kim Kardashian has too much ass, it's just silly.
