The MacBook Air is an amazing laptop. Great design. Thin and light. Powerful enough for most tasks. A few months ago, ultrabooks didn't hold a candle to the MacBook Air. And they struggled to sell just a few units. However, ultrabooks are catching up. Asus Zenbook Prime, Samsung Series 9 and Lenovo X1 Carbon are also great laptops and serious contenders to the MacBook Air. We have ultrabooks which have better screens, better keyboards and that are even lighter than the MacBook Air. And they are also becoming cheaper. A new wave of ultrabooks is coming, especially after the release of Windows 8, such as Acer Aspire S7. With so many new releases, the MacBook Air feels less and less unique. Is it time for Apple to refresh the line and blow every ultrabook away?
