The "RAZR" V3 is certainly the star of Motorola's new announcements. Like the V600 last year, the V3 is the new signature model in Motorola's lineup, designed to emphasize style and showcase the company's engineering talent.
The main selling point of this model is the "razor" thin profile. Using exotic materials and clever engineering, Motorola has managed to pack a complete, feature-rich phone into a package just 13.9 millimeters thick - half the thickness of most other clamshell models. And amazingly, they didn't skimp on features, adding a second color display and a camera. There is no thinner clamshell phone in world with these features.
The unique materials are much of what makes this design possible. Motorola seems to have taken a cue from Apple and its titanium laptops. In the V3, anodized aircraft-grade aluminum clads the exterior. Aluminum was chosen because it is much lighter than titanium, (the same reason Apple eventually switched to aluminum.) Plus it's easier to work with, and also recyclable (important in parts of Europe).

Magnesium is the material you'll see when you open the V3. It was chosen over aluminum for being moldable (for tricky hinge parts, etc.). Since magnesium is a full 18 times stronger than plastic, the inner casing could be made paper-thin without sacrificing durability.
And finally, a nickel-plated copper-alloy is used for the unique keypad. This unusal metal was chosen for being flexible, and also because it allows the eye-catching "spun" finish that radiates from the direction pad.
But wait - that's not all! You have to wonder if one of the engineers had some kind of bad childhood experience with plastic, because they even managed to avoid it with the outer display and camera lens. Instead, a special hardened glass is used, that is thinner, more resistant to scratching, and allowed them to place the LCD closer to the surface, further reducing the overall thickness.
