Huawei touts the latest version of its MateBook X Pro as the ultimate ultrabook as it weighs just 34.6 ounces (or 980 grams (g)) - however, it is about to be dethroned by an upcoming, possibly very similarly-named, rival from Honor, according to a new leak. The alleged addition to the MagicBook line might also debut as an "AI PC" and come packed with "exclusive" tech.
