My Book we've ever seen, but it possesses the otherworldly ability to live in the here and now and the hereafter. Analogies aside, the new My Book Live Duo is hailed as such: "a personal cloud storage system that combines the benefits of shared storage and remote access with double-safe backup or increased capacity of a dual-drive system with RAID." It's compatible with Mac and PC systems (and yes, Time Machine support is thrown in for good measure), and you'll find a pair of drives within the casing alongside an 800MHz CPU and an Ethernet port. WD's hawking these in 4TB (2 x 2TB) and 6TB (2 x 3TB) capacities, and if you weren't already sold, the units ship with support for the company's WD2go remote access platform -- something that's accessible via the web, iPad, iPhone, iPod touch or Android. Finally, there's a DLNA-certified media streaming badge, and it's available as we speak at select US retailers for $399.99 (4TB) / $499.99 (6TB).
