I've had a couple Asus laptops (not a Zenbook), and the multi-touch is pretty decent (well, once you dig into the settings and turn off pinch-zoom and all the fancy three-finger gestures). Still, Apple's multi-touch implementations are much better than "pretty decent". I would love a Windows equivalent to the Magic Trackpad; it doesn't even have to have all the gestures, two-finger scroll (both vertical and horizontal) and one, two, and three-finger tap-to-click (for left, middle, and right mouse buttons) on a big external trackpad would make me very happy (so long as it worked well).
