While its primary focus is netbooks, Chrome OS could eventually scale to a wide variety of devices. Google’s Chromium.org site contains visual explorations of how a Chrome OS tablet UI might look in hardware.
On tablets, the UI would be adjusted to handle larger touch targets. Initial explorations have maintained the same basic chrome layout, but enlarged the controls. Icons could be placed above tabs to provide larger, square targets. Panels would be placed along the bottom edge and could be opened with upward dragging motions.
Form Factors Exploration are available too.
