There aready exists tag for `asus`, and `zenbook` is sub-family of `Asus` ultrabook products. From `asus` tag [description][1]:

> ASUSTeK Computer Incorporated product range includes motherboards, laptops, servers and mobile phones.

Since this tag already includes laptops, I believe `zenbook` is unnecessary. We could also make the tag inclusive of `zenbook` to add ultrabooks to the listing. What do you think, community ?
