We wanted to add a Galaxy Note II to the mix, but this iPad Mini was the closest thing we had (size-wise).

Despite the minor variation in appearance, not all black rectangles are created equal. Compared to the Galaxy Nexus—the phone it succeeds—the Nexus 4 is a hair heavier (139 g vs 135 g), thicker (9.1 mm vs 8.9 mm), and wider (68.7 mm vs 67.9 mm).
