Keyboard and Buttons

The Quantum is one of the few Windows Phones sporting a slide-out QWERTY keyboard. This keyboard is unique as its shift and function ("fn") keys are their own separate buttons. They are next to the keyboard, not integrated as keys. The keyboard is particularly large, which makes it easy for people with larger hands to use.

Other Windows Phones with physical keyboards are the Dell Venue Pro and HTC 7 Pro, making it a rare-breed of Windows Phone.

The Quantum is also one of the only Windows Phones with a physical Start button, rather than the capacitive buttons seen on other Windows Phones.
