Zenbook Duo review: are two laptop screens better than one?

Asus machine is best yet at being a laptop on the go and a dual-screen productivity beast at the desk

Portable computers with multiple touchscreens have long been a feature of sci-fi films. But while several manufacturers in the real world have tried to make dual-screen laptops, none of them have really worked out.

Typically this is because they have tried to do too much with too many compromises. Now Asus thinks it has cracked it with a new dual-screen machine that also has a full-size detachable physical keyboard.
