| Bottom line | The business-oriented Lenovo ThinkPad X1 has a few quirks, but is otherwise a very impressive business-oriented ultrabook with strong crossover potential. | The business-oriented Lenovo ThinkPad X1 adds must-have features for 2013, and remains a very impressive business-oriented ultrabook with strong crossover appeal. | For those looking for something more than a feature-light ultrabook, the gamer-friendly Lenovo IdeaPad Y500 is close to brilliant, and several configurations are currently available at a deep discount -- but I can't believe it doesn't have a touch screen. | 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. |
