Asus is launching new Zenbooks apparently in the hopes of appealing to everyone. What once consisted of only Ultrabooks now features six devices, one of which is not an Ultrabook. Most recently Asus has announced the UX42 and UX52. It looks like the company is keeping somewhat reasonable conventions though, devices prefixed with ‘UX’ all seem to be Ultrabooks while the lone ‘U’ device is a non-Ultrabook (even if it is still relatively thin and light).
