Asus turns the trackpad into a 5.9in touchscreen display. Multiple displays are typically a good thing. Whether you're a desktop creator with two or more monitors, or a laptop user who likes to dock to an external panel, having extra screen real estate can be a real boon for productivity. And who can forget the dual-screen Nintendo DS? Arguably one of the most enjoyable games consoles of all time.

Point is, there are many ways to augment the computing experience with a secondary display, and for mobile purposes, you don't have to wait for next year's Microsoft Surface Neo as Asus has already shoehorned two displays into a super-sleek laptop dubbed the ZenBook 14 UX434F.
