The Wolverine ESP 5000 hard drive is tailor-made for digital-photography enthusiasts who want to view their photos from anywhere. Conveniently, the ESP 5000 works like any other USB 2.0 mass storage device: Just jack it into your PC's USB 2.0 port, and use Windows Explorer to transfer images, music, video, or data into the preconfigured folders, and the content will be visible on the device. Measuring 5.3 by 2.8 by 0.9 inches and weighing 10.2 ounces, it's suitable for toting in a bag, not a pocket. The ESP 5000's 3.6-inch TFT LCD has an adjustable backlight and offers 320-by-240-pixel resolution. The ESP500 comes in capacities ranging from 80 to 250 GB, and retails starting at $300.
