Western Digital's My Book family updated to 1.5TB

Western Digital just upped their My Book family of storage solutions to 1.5TB. The update apparently applies to the magnificently confusing range of products including the World Edition, World Edition II, Pro Edition, Pro Edition II, Premium Edition II, Premium ES Edition, Premium Edition, and Essential Edition... which isn't all that essential considering the alternatives. However, the obtusely worded press release and lagging web site and on-line store has us scratching our collective heads. So let's just say that the My Book World Edition NAS products have been updated and call it a day.
