The new Windows Phone 7 added to AT&T is the LG Quantum. The Quantum is the Windows Phone 7 addition slider phone with a full QWERTY keyboard. Despite this device not being as sleek or elegant as the other phones in the Windows Phone 7 line up it is every bit as powerful as the other devices. The clincher for this phone is the excellent keyboard that it has. The 4-row keyboard is very spacious, with good feel, and large buttons. This makes for a very finger friendly device which it will be easy for anyone to text with whether your fingers are big, like mine, or small. The only thing left for all of these Windows Phone 7 devices is to actually go out and be used by consumers before we decide if it is good or not, but in my opinion Windows Mobile has finally stepped up their game and deserve some recognition.
