In Pictures: The New Windows Phone 7 Handsets

The behemoth of HTC's WinPho7 lineup has a 4.3-inch screen, a software keyboard, 576MB of RAM, 16GB of storage, and a 5-megapixel camera with 720p video capture. Best of all, it has a kickstand. Look for the HTC HD7 on T-Mobile in mid-November for an as yet unannounced price.

Dell's foray into Windows Phone 7 handsets has a 4.1-inch screen and a QWERTY keyboard. Other specs include a 1GHz processor and a 5-megapixel camera, but T-Mobile is keeping other details under wraps. It'll be available in time for the holidays directly from Dell and from select retailers (but not, it seems, from T-Mobile stores).

LG's lone WinPho7 offering for the United States is the Quantum (pictured at left; at right is the LG Optimus 7, which will launch in Europe and Asia). The Quantum has a slide-out QWERTY keyboard, a 3.5-inch display, 256MB of RAM, 16GB of storage, and a 5-megapixel camera. Its standout feature is a preloaded application called Play To, which permits users to stream video, photos, and music to other DLNA-supported devices, such as computers and connected televisions. Like all other AT&T Windows Phone 7 devices, it will cost $200 this holiday season.

The HTC 7 Pro will land on Sprint early next year, in line with previous reports that CDMA Windows Phone 7 devices would not be arriving until the first half of 2011. This model has a QWERTY keyboard, and at 6.47 ounces it's the heaviest phone in Microsoft's initial portfolio. The screen size is 3.6 inches, and the phone carries a 1GHz processor, 576MB of RAM, 16GB of storage, and a 5-megapixel camera with 720p video capture.

Samsung's Focus will be the first Windows Phone 7 device out of the gate in the United States, launching on November 8 on AT&T for $200. Despite its roomy 4-inch screen, the Focus is the lightest phone in the initial Windows Phone 7 lineup, with a weight of 4.07 ounces. It also has the longest battery life--an estimated 6.5 hours of talk time. On the downside, 8GB of storage could fill up fast. Other specs include 256MB of RAM and a 5-megapixel camera with 720p video capture.

Though the HTC 7 Surround comes with a slide-out mechanism, it doesn't have a physical keyboard. Instead, you get a sliding speaker for kicking out the jams or for having a conversation via speakerphone. Some other specs: a 3.8-inch screen with 480-by-800 resolution,a 5-megapixel camera with 720 video recording, 576MB of RAM, and 8GB of internal storage. Look for the HTC 7 Surround on AT&T for $200.
