Short extract: An Ultrabook such as the Asus ZenBook UX31 might be the ultimate luxury for frequent travellers with deep pockets, but we suspect most people would prefer to carry a little extra weight and save a few hundred pounds by opting for a traditional ultra-portable laptop such as this Asus U46SV.

Conclusion: A great mid-range laptop that won’t weigh you down when on the move – if an Ultrabook doesn’t appeal, the U46SV is the next best thing
