| Bottom line | 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. | 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. | Slightly less conservative-feeling than the average ThinkPad, the well-made ThinkPad Twist offers one of the better tablet modes from the first wave of
Windows 8 convertibles. |
