With its clamshell design and dual touchscreens, Acer's Iconia makes a clear design statement: Touch is in. When closed, the Iconia looks like an ordinary laptop. But when open, it resembles no other notebook or slate. At the heart of the Iconia's navigation is the Ring interface. You activate the Ring by putting five fingers on the bottom display, which Acer refers to as the "hand screen" or the "navigation screen." Up pops up a wheel that you can scroll through to access apps optimized for finger navigation.
