HTC 7 Pro, the name speaks for the phone - it is a WP7 smartphone with QWERTY keyboard. The QWERTY keyboard of HTC 7 Pro can be accesed by sliding the phone down. Of course, the phone has a virtual QWERTY as well, since the 3,6" display is large enough for it, but some people are just too used to the physical touch and HTC 7 Pro is the smartphone they need. The rest of the specs and features are in accordance with what means "top end smartphone" and only the limitations of the WP7 could cause you some additional questions, but hopefully, they will be erased one by one with the future updates.
