We have seen webOS interface on the Palm range Pre and Pixi. However, these devices are smartphones with small screens. How webOS will work on HP's Opal and Topaz tablets as well as future touch-only smartphones. The interface on a larger screen will now be split into panels depending on the screen size of the device. A smartphone would only see a single screen, PreCentral found, but larger tablets would see two or three panels, such as a list of messages side-by-side with the message bodies.
