| Bottom line | One of the few standout products from the first wave of
Windows 8 laptops, the Acer Aspire S7 proves that Apple does not have a monopoly on great design. | The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience. | The Asus Zenbook UX51Vz-DH71 is a nice fit for anyone looking for premium looks and performance in a
Windows 8 laptop who is willing to pay for it. | This year's
MacBook Air opts for gradual improvements rather than anything revolutionary, but lowered prices continue to make it the go-to mainstream recommendation for any MacBook owner-to-be. |
