The Asus VivoBook S15 S530UA ($500) proves that innovation isn't limited to premium laptops. This excellent mainstream system is truly one of a kind. Inspired by the laptop maker's pricier ZenBook S, the VivoBook S15 features Asus' new ErgoLift hinge, which angles the keyboard for a more comfortable typing experience. As if that weren't unique enough, the VivoBook S15 is available in several striking color schemes, including a gorgeous turquoise green and a blinding yellow.
