Design

The Quantum's design isn't very inspiring, but it is a solid piece of hardware. It weighs 6.2 ounces, making it pretty heavy. Thankfully, it's pretty compact at 4.7 inches tall by 2.3 inches wide by 0.4 thick to make it a little more manageable.

Keyboard

What makes the Quantum different from other Windows Phone 7 devices is the slide-out QWERTY keyboard. It's spacious with large, rectangular buttons. The function and shift keys are located off to the left side, which is fine, but they're a bit small and set slightly below the phone's surface, making them hard to press.

Landscape support is currently limited on Windows Phone 7, so even when you slide open the phone, the Start screen remains in portrait mode.

Picture quality

The camera didn't fare so well with indoor shots, as images came out grainy and dull. It did better outdoors, however, and video quality was also good.
