The LG Quantum is the lone QWERTY slider on AT&T's initial Windows Phone 7 lineup. We dare say it feels a tad on the cheap side, but that's not really a fair assessment. The keys are nice and clicky, and very well space. It helps that it's only a four-row keyboard and they're not cramming too many in one space. The slider mechanism is stiff, but not too stiff, and has a good spring to it.

The 3.8-inch screen is a dandy. Not as bright as Super AMOLED that you'll see on the Samsung phones, but for most people (like 99 percent of them) it'll be more than adequate thanks to its size.

More pics after the break.
