对苹果iPhone X的五个重大疑问

经过几个月的猜测和传闻之后，苹果终于揭开了iPhone X的面纱，并详细介绍这款价格昂贵的手机（售价高达1,000美元）有哪些功能。

周二，在苹果新总部Apple Park举办的首次发布会上，苹果推出了iPhone X。这款手机的屏幕几乎覆盖了整个正面，并且配备了强大的处理器，可以处理复杂的应用和视频游戏。这款手机还支持无线充电，并推出了一项新功能Face ID。苹果表示，这项功能可以显著改善智能手机的安全性。

当然，苹果高管称iPhone X是“未来的智能手机”。或许他们说得对。但还有一些重要问题，苹果并没有给出答案。下面是其中最热门的几个问题：

Face ID是否像苹果说的那么可靠？

在发布会上，苹果大力宣传新Face ID面部扫描识别功能的可靠性，称其在准确性和安全性方面，远远优于Touch ID指纹传感器。苹果软件工程高级副总裁克雷格·费德里吉在演示这项功能时，效果似乎还不错 — 第一部手机没能识别出他的脸，他拿起一部备用手机，擦了擦脸才识别成功。很显然，他已经接触Face ID很长时间，很清楚哪个角度效果最佳。当数百万人拿到iPhone X并开始使用的时候，其面部扫描仪是否还能达到苹果高管希望我们相信的效果？

其他设备的面部扫描仪只有在特定角度下的效果最佳，例如三星的Galaxy S8，有些手机的面部识别功能完全无效。另外，还有一些有关安全性的问题，以及黑客能否轻易骗过扫描仪。

苹果在发布会上表示，其工程师建立了应对黑客攻击的防护措施，希望解决这些担忧。苹果还表示Face ID被他人破解的概率只有百万分之一（指纹传感器为五万分之一）。但我们要在看到它在现实世界的表现之后才能相信。

iPhone X的外壳是否容易损坏？

iPhone X和iPhone 8均采用了玻璃背面。苹果称玻璃很结实，但同样采用玻璃外壳的iPhone 4在跌落时很容易碎裂。现在的玻璃技术比2010年更加强大，这意味着外壳碎裂的可能性大幅降低，但它到底有多坚固取决于所用的材料。无论如何，为iPhone X装上保护壳或许是个好主意。

上市后的供货量有多少？

在iPhone X发布之前，笔者从其他报道中了解到，苹果遭遇了生产问题，产品的供应量可能达不到预期。预计消费者对iPhone X将有大量需求，因此苹果的初期供货将在多短时间内售罄？更糟糕的是，如果没有在10月27日之前预订，我们在产品上市后的短期内是否很难买到这款手机？

iOS 11的集成功能可靠吗？

iPhone X取消了Home键，需要通过基于软件的新手势来激活手机功能。例如，在之前版本的iPhone手机上，查看已打开的所有应用，你只需要轻按两下Home键。而iPhone X取消了Home键，要想访问这个窗口，你需要从屏幕底部向上滑动屏幕。苹果表示，新手势体验出色，可以像Home键一样访问手机的功能。但并不清楚这些手势是否方便。

会有许多人愿意花如此高的价钱买一部手机吗？

iPhone X确确实实非常昂贵。64GB版的售价为999美元，256GB的售价竟然高达1,149美元。你会花这么多钱来买一部智能手机吗？即便按两年分期购买一部iPhone X，你每个月至少也要支付49.91美元。这样一部新智能手机真得物有所值吗？显然苹果是这样想的。（财富中文网）

After months of speculation and rumors, Apple has unveiled the iPhone X and detailed what the luxury device —it costs $1,000—can do. Kinda.

At its first press event at its new Apple Park headquarters on Tuesday, Apple took the wraps off its iPhone X. The device comes with a screen that nearly covers its face and has a powerful processor for handling sophisticated apps and video games. It also comes with the ability to wireless charge its battery along with a new feature, called Face ID, that Apple says will dramatically improve the smartphone's security.

Apple executives, of course, called iPhone X the "future." And they may be right. But there are still some big questions the company hasn't answered. Here's a look a some of them:

Is Face ID as reliable as Apple says?

During its event, Apple (aapl, -0.40%) touted the reliability of the new Face ID face scanner, saying it was better than the company's Touch ID fingerprint sensor in both accuracy and security. But when Apple senior vice president of software engineering Craig Federighi showed off the feature, it seemed to work well—that is, after the first device failed to see his face, he moved to a backup, and wiped his face to help it work. And that was someone who has been working with Face ID for some time and knows exactly at what angle it works best. When millions of people get an iPhone X and start using the device, will its face scanner work as well as Apple executives would have us believe?

In other devices, like Samsung's Galaxy S8, face scanners work best at certain angles and not at all from others. And there are very real questions about security and how easily hackers can dupe the scanner.

Apple tried to address those concerns during its event by saying that its engineers built safeguards to counter hacking. Apple also said its Face ID can only be duped one out of 1 million tries (versus 1 in 50,000 tries using the fingerprint sensor). But let's see it in the real world before we believe it.

How prone to damage is the iPhone X's enclosure?

Both the iPhone X the iPhone 8 have glass backplates. While Apple says the glass is strong, the company's iPhone 4, which also used glass, was prone to cracking when dropped. Glass technology is stronger now than in 2010, which means it might be less likely to be damaged, but exactly how strong depends on the materials that companies use. Either way, using a protective case for the iPhone X may be a good idea.

How many units will be available at launch?

Before the iPhone X's unveiling, we heard reports that Apple was having manufacturing problems and that it may not have as many units available as it would have liked. With demand for the iPhone X expected to be heavy, how quickly will Apple sell out of its initial supply? And even worse, will we have trouble getting it anytime near its launch if we don't pre-order on Oct. 27?

How reliable is iOS 11's integration?

With no home button, the iPhone X requires some new software-based gestures to activate features. For instance, to see all the apps open on older iPhones, you need only to double-tap the home button. With no home button, the iPhone X now gives you access to that pane by swiping up from the bottom of the screen. Apple indicated that its new gestures will work well and get you the same access to features as with the home button. But it's unclear how convenient those gestures will be.

Will many people really want to pay that price?

The iPhone X is really, really expensive. The 64GB version costs $999, and the 256GB option will cost you a whopping $1,149. Will you pay that much for a smartphone? Even the installment plans, allowing you to pay for the iPhone X over a two-year period, will cost you at least $49.91 per month. Is that really a good value for a new smartphone? Apple apparently thinks so.
