The HTC HD Mini is based on its big brother the HTC HD2. HTC has packed the same interface into the HD Mini in a more compact form. The HTC HD Mini includes a capacitive touch screen, 512MB ROM, 384MB RAM, 3.2" HVGA display, 5MP camera and the usual support of 3G and GPS. The phone will be powered by Windows Mobile 6.5 and HTC Sense. The differences between the HTC HD Mini and the HD2 are minimal but it's clear that the device suffers from some performance issues due to the 600mhz processor.
