I think this is great: a book-shaped network storage device. What's great about it is not that it's book-shaped, but that it's designed to act like a book. That shows an understanding of how to incorporate technology appliances into people's environments and a valuable way of humanizing this technology through analogy. Plus, the engineers probably conceded optimal functionality (neighboring books will probably block some of the radio waves, and heat dissipation is certainly worse than in a standalone device) in favor of a better user experience, which is a tradeoff that should happen more often.
Here's a picture of an earlier one from the same company that has a more book-like design, but doesn't sit upright like a book:
