The Asus Zenbook S 14 (UX5406) is a super thin and super light ultrabook. It's durable and made from premium materials. It comes with a touchscreen and you can use a stylus for notes. Performance is good, and the new Intel processors allow not just power, but also record-breaking battery life compared to comparable devices from previous generations. It's true that it's priced at a pretty steep premium, but for professionals who travel often it's definitely worth the investment.
