When you take the Devour out of the box, you are greeted with a very smooth, silver-grey aluminum exterior. The first time I handled it I was taken aback by the heft to it. It is relatively comparable in weight to my old phone, the Blackberry Storm, but the sleeker form factor made this heft surprising. The phone also feels rock-solid. There is no creak or "play" in any of the components. The screen is held firmly in place by a robust spring open/close mechanism, which produces a very pronounced and satisfying "click/clack" when opening or closing it. The aluminum finish looks and feels like the exterior of a Macbook Pro, and is very appealing in both look and feel.
The square on the bottom-left is a small, touch-sensitive navigator. It allows you to scroll through pages or screens on a per-item bases, and is also clickable. I've used it a relatively small amount, but when I do use it, it's usefulness is entirely utilized, and seems to be a good replacement to a trackball.
The back dawns the same aluminum finish, and the black portions have a very comfortable rubberized feel. The right side houses the camera, as well as the headphone jack, which fits the standard 3.5mm headphone jack size. Along the upper edge, you can see the black camera button (left), a miscellaneous button, set as voice commands, and the volume buttons (2 rightmost). Along the bottom, below the blue line, is where the battery and SD cards are side-loaded into the phone. The door extends over the length of the phone, and is very solid, and fits very snug. I was a bit worried initially that it would creak or wobble, but the fit is perfect, and has been perfect so far. The side-loading also allows the battery and microSD cards to be swapped out independently of one another.
Here's a view of the top, where you can also see the power/lock button, and the headphone jack.
