近日，国外某网站放出了苹果Macbook Air笔记本的相关测试数据，并将它和其它苹果笔记本进行对比。
Macbook Air分为高配版和低配版，其中低配版的售价为1799美元（换算称人民币约为13000元），不过加上各项税率，国内的行货最终价格可能会在16000元以上。
低配版MBA采用了超小封装的英特尔酷睿2双核处理器1.6GHz，GM965芯片组（集成GMA X3100显示芯片）、2GB DDR-667内存和80GB的1.8英寸4200RPM硬盘（低转速、低噪音、低发热量）。
高配版的售价为3098美元，它的处理器主频为1.8GHz，并加入了64GB的SSD固态硬盘（主要就贵在这儿了），对提升系统效能很有帮助。此外，原装的外置光驱售价为99美元。

测试结果是：MBA是史上最慢的Macbook，但仍然能满足用户的基本日常应用。考虑到它的体型，这样的结果也在意料之中吧。
