'The Quantum is heavy.'
'It's quite heavy at 4.7 by 2.3 by .6 inches (HWD) and 6.2 ounces.'
'Built for both business and entertainment, the LG Quantum is probably the most versatile of the latest Windows 7 phones, thanks to that generous QWERTY slider, while the Samsung Focus just flaunts a Super AMOLED screen and the HTC Surround specializes in Dolby sound on the go for the music and video addict. '
'The phone features a full QWERTY keyboard and a nice 3.5-inch WVGA resolution touchscreen display. '
'Colours are impressive too, as when the screen is viewed indoors they look very bright and vivid.'
'It has a decent sliding keyboard and we like the dual home screens too. '
'This smartphone also uses Samsung's new TouchWiz 2.0 user interface, with user-customizable widgets and multiple home screens. '
'Its mechanism is tight and the phone opens and closes smoothly and easily.'
