Samsung rarely displays S60 phones, and S60 Touch UI might not be a success on their side, so this time they opted for Instinct UI.
From the video, the device looks rather small, or maybe Chris Ziegler from Engadget has gigantic fingers.

What we can clearly see is the web browser, and the usual finger-scrolling that we saw in devices such as Apple iPhone and Nokia N800. The main options on the sides are the Zoom buttons, but what I really wanted to see is the keyboard, but I believe we will be in for more videos and adverts once it launches itself into the market.
