The HTC HD2, HTC internal codename Leo, is a smartphone with Windows Mobile 6.5 operating system. Supportive you can use most functions on the in-house user interface HTC Sense, which is, so to speak about the actual operating system Windows Mobile as "Skin". HTC Sense was developed because the now outdated Windows Mobile, has been designed for use with pen-driven PDAs and thus was not optimal for finger control to capacitive touch screens. The Windows Mobile user interface is used only for rarely used settings of the phone, for example, when searching for information, or to download apps from the in-house Microsoft Marketplace. The HD2 is the first Windows Mobile phone that has a capacitive touchscreen and supports multi-touch.
