| Bottom line | The latest Samsung Series 9 goes extra-big, and the gamble pays off with the most portable and comfortable 15-incher you're likely to find. However, its high price and lack of higher-end features don't make it the best value. | If you're looking for a beautifully built, extremely thin, light, and portable ultrabook, the Samsung Series 9 rises above the competition. It may lack a few top-end features, but it's a perfect ultraportable for those who can afford it. | The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience. | The newly redesigned MacBook Pro with Retina Display combines an amazing screen with just enough of the
MacBook Air design to feel like a new animal, and to take its place as the best of the current MacBook breed. | 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. |
