We covered much of the design aspect of the X10 in our earlier preview. But for convenience, here's a quick recap of the X10's human curvature design. A straight-on flat surface with curves running along its sides and rear portrays a fine balance of sophistication and build quality on the X10. Its human curvature design does fit into the palm nicely, if you have a sizeable hand to grasp the X10 and its 4-inch capacitive screen. Also, its physical buttons were adequately raised for easy access.
