HTC’s HD2 is the first Capacitive based screen.
Capacitive means generally finger based usage, but with Windows Mobile OS still sticking with old UI tailored towards usage of stylus, this was kind of a downfall when you need to mess with Settings or some feature deep inside Windows Mobile.

Now HTC HD2 receives a Stylus and that means one more point added to the pros of the already powerful HD2.
