So, that's the electronics, that's how we fit a Mac inside the world's thinnest notebook.
以上就是关于电路板的介绍，也是我们能把Mac装进这么薄的笔记本儿的原因。
So let's take a look at some of the other features.
让我们来看看其他一些特性。
On one of the sides, we've got a MagSafe connector.
在机身的一侧，我们设置了一个MagSafe接口。
We've got a smaller 45W power adapter that also comes with the MacBook Air.

在机身的另一侧，我们设置了一个可打开的USB 2翻盖接口，一个支持数字和模拟视频的Micro-DVI接口，以及一个耳机插孔。
And maybe most importantly, we've built in the most advanced wireless networking technology, 802.11n right into MacBook Air, along with Bluetooth 2.1 + EDR.
最重要的是，我们已经在MacBook Air中内置了最先进的无线网络技术802.11n，以及蓝牙2.1+EDR。
So the latest and greatest in wireless technology, the MacBook Air was built to be a wireless machine.
因此，作为无线技术领域最先进的产品，MacBook Air的设计初衷就是要成为一台无线设备。
Now, no matter how hard you look, one thing you're not gonna find in a MacBook Air is an optical drive.
接下来，不管你多仔细地找，你都不会在MacBook Air上找到光驱。
If you really want one, we've built one.
如果你想要一个光驱，我们也做了设计。

But you know what? We don't think most users are gonna miss the optical drive, we don't think they're gonna need an optical drive.
但是你们知道吗？我们不认为大多数用户会想念光驱，我们不认为他们会需要光驱。
Because again, the MacBook Air was built to be a wireless machine.
因为还是那个原因，MacBook Air是要打造成为一台无线设备的。
So what do we normally do with optical drives?
我们通常会用光驱干什么呢？
We play movies, right? We install software, we make backups, and we burn music CDs sometimes, for our cars usually.
播放影片，是吧？安装软件、备份文件，有时还会刻录音乐光盘，通常是为了我们的汽车。
Well, guess what? We have a much better way to get movies onto our computers now.
可是现在的情况呢？我们有把电影传到电脑上的更好的方法了。
We can wirelessly rent them from iTunes Movie Rentals right on our MacBook Air.
我们可以通过MacBook Air上的iTunes Movie Rentals，利用无线来租赁电影。
We have a much better way than burning CDs for our car, most of us have iPods in our cars now.
我们有比为汽车刻录CD的更好的方法了，因为我们大多数人现在都在车里放了ipod。
For making backups, we now have time machine and time capsule to wirelessly backup our notebooks.
而至于备份，我们现在有时间机器和时间胶囊来无线备份笔记本电脑了。
What about installing software? Well, we're gonna do that wirelessly, too.
那安装软件呢？我们也可以通过无线来做到。
We've innovated in a way only Apple can to give a comprehensive solution to this problem.
我们以一种只有苹果才能做到的方式进行创新，为这个问题提供了一个全面的解决方案。
We have a new feature on MacBook Air, built right into the operating system called Remote Disc.

And so once they've accepted it, you'll see what's in their optical drive, and you can even you have Mac installer discs inside a Windows PC.
一旦他们点击了接受，你就可以看到他们的光驱里有什么，甚至可以在Windows电脑里发现Mac的安装盘。
