And while the MacBook Air's specs are inferior to those found on the cheaper MacBook, they compare more favorably when you look at other ultraportables, where a price premium is always exacted. For instance, both the Sony VAIO TZ150 and Toshiba Portege R500 cost hundreds more than the MacBook Air and feature slower CPUs and half the RAM as the Air.|
Although it shares a desktop footprint with the standard black and white MacBooks, the first thing you notice about the Air is its aluminum chassis--similar to the one found on the MacBook Pro, and much more fingerprint resistant than the standard MacBooks.
虽然MacBook Air的技术规格不及价格更低的MacBook，但是和其它超便携类笔记本相比却更有优势。。。。例如，索尼VAIO TZ150和东芝Portege R500比MacBook Air都要贵几百美元，但是两者的CPU却更慢，而且内存是MacBook Air的一半。
虽然“所占桌面面积”和标准黑白色MacBook相同，你注意到的第一样东西是MacBook Air的铝制外壳--这点类似MacBook Pro；但是，MacBook Air比标准MacBook抗指纹度大地多。
Picking it up, the MacBook Air feels a little heavier than you would expect from looking at it, even though it's only 3 pounds. At the same time, it feels very sturdy and solid, thanks in part to the aluminum construction, and we'd have no qualms about carting it around with us all day.
拿在手上，MacBook Air感觉要比你刚才看上去时要重一点，虽然，它其实只有3磅（1.36千克)。 同时，感觉非常硬朗、坚固，这要部分归功于采用铝制造。如果一天到晚都拿着也不会感到不适。
By way of comparison, the VAIO TZ150 features an 11.1-inch screen and weighs only 0.3 pound lighter than the Air, and the Portege R500 is 0.6 pound lighter than the Air with a 12.1-inch screen.
相比之下， VAIO TZ150的屏幕为11.1英寸、重量只比MacBook Air多0.3磅，而Portege R500比MacBook Air要轻0.6磅、拥有12.1寸的屏幕。
The MacBook Air includes an iSight camera and mic, and an LED-backlit display that works with an ambient light sensor to adjust the screen brightness in response to the light in the room.
The keyboard--the same full-size version found in other MacBooks--has backlit keys that are also controlled by the ambient light sensor, although we had to adjust the room lighting a good deal to see any difference.
The revamped trackpad is large, measuring nearly 5 inches diagonally, and it works with new multitouch gestures. Other MacBooks let you do things like use two fingers to scroll through documents--this one lets you use three fingers to go forward and back in your Web browser history, and use your thumb and forefinger to zoom in and out of documents and photos--much like on the iPhone.
The three-finger forward/back gesture was immediately useful, and we're already missing it when using other laptops. Apple tells us these new gestures won't be available on older MacBooks as a firmware upgrade, as the hardware behind the new trackpad is different.
Another noteworthy new feature is the remote disc function. Since the Air lacks an optical drive, you can instead remotely use the optical drives of other systems, PC or Mac, as long as they're on the same network.
The setup was a little cumbersome for the "host" PC--requiring us to insert the OS X disc that came with the Air, run a small setup program, and then find and turn on "CD and DVD sharing" in the Windows control panel (the documentation could have been a little clearer on what you need to do to on the Windows side).
安装远端光驱对于“主机”来说有些麻烦--需要插入一张MacBook Air随机安装OS X盘，运行一个小安装软件，然后在Windows控制面板下打开"CD和DVD共享“（说明书上也许对此有更清楚的说明）
Once we set it up, however, it worked like a charm. You won't be able to stream DVD movies or music CDs via remote disc, but it's fine for getting files and installing apps. A matching external USB DVD burner is available from Apple for $99, but any USB DVD drive should work.
The display offers the same 1,280x800 native resolution as the standard 13-inch MacBook, but the Air's LED-backlit screen means its lid is thinner with an image that was somewhat brighter, at least with both systems set to max brightness.
The real key to finding out whether the MacBook Air is right for you lies in its stripped-down set of ports and connections. Those who regularly use more than one USB device, or need FireWire, an SD card slot, or an Express card slot will find the single USB jack too limiting.
要看MacBook Air对你是否适合的真正关键在于缩减后的端口和连接。 经常要用到一个以上USB设备、或需要FireWire，一种SD卡槽、或Express卡槽的人会发现单USB口的局限性太大了。
