They're actually both western digitals, you must have missed the poll. Yeah I don't think it's bait advertising but not sure. It was an anniversary sale "while supplies last" so I'm kinda surprised they even gave me a replacement instead of saying "sorry they're all gone." I'll probably swap it for the more expensive one unless someone here thinks I should keep the My Book. It doesn't come with backup software like the Media Center, but according to the sales guy it has better cooling. Any more thoughts would be appreciated cause they said if I do decide to swap I gotta do it pretty soon.
