One of the features of the iPhone that blew me away was the way you can scroll through your list of contacts by tapping your finger on the screen and dragging it down the list. iContact rips this feature for Windows Mobile devices, allowing you to use your forefinger, index finger, or even your pinky, to peruse your contacts using a system that's sensitive to forces of acceleration and deceleration, known as 'inertia scrolling'.
The program enables you to list all your contacts alphabetically, scrolling includes inertia and allows you access to the details of each contact with a simple tap. It works okay, but it's far from seemless, and if you have a PDA with a lightweight processor then you'll experience some degree of lag when scrolling, which gets annoying after a while. It's still in development stage though so hopefully these problems will be ironed out before too long.
While it's rather a crude copy of the iPhone's fluid intertia scrolling capabilities, iContact provides an interesting way of listing contacts for those with a powerful enough processor.
