If you are buying a laptop for a specific purpose, then you need to make sure that it does the job. However, the MacBook Air seems to be a better contender.
I have recently come to like very much the Asus Zenbook Touch UX31A.
I would like a decent, light, fast and portable laptop. I'm off to university – my first year for a BSc in Economics – and I need advice on which laptop to get.
