Windows Phone 7: Hands-On
The LG Quantum is the only sideways slider Windows Phone 7 device that offers a full QWERTY keyboard. It is probably the thickest of the Windows Phone 7 devices being displayed by U.S. carriers. Despite the thickness, it has a small-ish footprint due to the smaller screen.
It has a nice, rounded feel to it, and feels like a bar of soap, a trend I've noticed among phones of late. It won't be a problem to put in a pocket.
The buttons on the front work well, but I didn't think the slider had a good feel to it. It was a bit rough, and it felt as though there might be some sand or grit in the slider mechanism somewhere.
Underneath, the keyboard felt roomy and easy to work with. The keys were a bit on the flat side, making them somewhat difficult to tell apart, but they had good travel and feedback. It was a four-row keyboard, and had navigation keys, but not specialized buttons for internet characters.
The buttons along the right side of the device worked fine, and the 3.5mm headset jack on top rounds out the hardware features.
