經(jīng)過幾個(gè)月的猜測(cè)和傳聞之后，蘋果終于揭開了iPhone X的面紗，并詳細(xì)介紹這款價(jià)格昂貴的手機(jī)（售價(jià)高達(dá)1,000美元）有哪些功能。

周二，在蘋果新總部Apple Park舉辦的首次發(fā)布會(huì)上，蘋果推出了iPhone X。這款手機(jī)的屏幕幾乎覆蓋了整個(gè)正面，并且配備了強(qiáng)大的處理器，可以處理復(fù)雜的應(yīng)用和視頻游戲。這款手機(jī)還支持無線充電，并推出了一項(xiàng)新功能Face ID。蘋果表示，這項(xiàng)功能可以顯著改善智能手機(jī)的安全性。

當(dāng)然，蘋果高管稱iPhone X是“未來的智能手機(jī)”。或許他們說得對(duì)。但還有一些重要問題，蘋果并沒有給出答案。下面是其中最熱門的幾個(gè)問題：

Face ID是否像蘋果說的那么可靠？

在發(fā)布會(huì)上，蘋果大力宣傳新Face ID面部掃描識(shí)別功能的可靠性，稱其在準(zhǔn)確性和安全性方面，遠(yuǎn)遠(yuǎn)優(yōu)于Touch ID指紋傳感器。蘋果軟件工程高級(jí)副總裁克雷格·費(fèi)德里吉在演示這項(xiàng)功能時(shí)，效果似乎還不錯(cuò) — 第一部手機(jī)沒能識(shí)別出他的臉，他拿起一部備用手機(jī)，擦了擦臉才識(shí)別成功。很顯然，他已經(jīng)接觸Face ID很長時(shí)間，很清楚哪個(gè)角度效果最佳。當(dāng)數(shù)百萬人拿到iPhone X并開始使用的時(shí)候，其面部掃描儀是否還能達(dá)到蘋果高管希望我們相信的效果？

其他設(shè)備的面部掃描儀只有在特定角度下的效果最佳，例如三星的Galaxy S8，有些手機(jī)的面部識(shí)別功能完全無效。另外，還有一些有關(guān)安全性的問題，以及黑客能否輕易騙過掃描儀。

蘋果在發(fā)布會(huì)上表示，其工程師建立了應(yīng)對(duì)黑客攻擊的防護(hù)措施，希望解決這些擔(dān)憂。蘋果還表示Face ID被他人破解的概率只有百萬分之一（指紋傳感器為五萬分之一）。但我們要在看到它在現(xiàn)實(shí)世界的表現(xiàn)之后才能相信。

iPhone X的外殼是否容易損壞？

iPhone X和iPhone 8均采用了玻璃背面。蘋果稱玻璃很結(jié)實(shí)，但同樣采用玻璃外殼的iPhone 4在跌落時(shí)很容易碎裂?，F(xiàn)在的玻璃技術(shù)比2010年更加強(qiáng)大，這意味著外殼碎裂的可能性大幅降低，但它到底有多堅(jiān)固取決于所用的材料。無論如何，為iPhone X裝上保護(hù)殼或許是個(gè)好主意。

上市后的供貨量有多少？

在iPhone X發(fā)布之前，筆者從其他報(bào)道中了解到，蘋果遭遇了生產(chǎn)問題，產(chǎn)品的供應(yīng)量可能達(dá)不到預(yù)期。預(yù)計(jì)消費(fèi)者對(duì)iPhone X將有大量需求，因此蘋果的初期供貨將在多短時(shí)間內(nèi)售罄？更糟糕的是，如果沒有在10月27日之前預(yù)訂，我們?cè)诋a(chǎn)品上市后的短期內(nèi)是否很難買到這款手機(jī)？

iOS 11的集成功能可靠嗎？

iPhone X取消了Home鍵，需要通過基于軟件的新手勢(shì)來激活手機(jī)功能。例如，在之前版本的iPhone手機(jī)上，查看已打開的所有應(yīng)用，你只需要輕按兩下Home鍵。而iPhone X取消了Home鍵，要想訪問這個(gè)窗口，你需要從屏幕底部向上滑動(dòng)屏幕。蘋果表示，新手勢(shì)體驗(yàn)出色，可以像Home鍵一樣訪問手機(jī)的功能。但并不清楚這些手勢(shì)是否方便。

會(huì)有許多人愿意花如此高的價(jià)錢買一部手機(jī)嗎？

iPhone X確確實(shí)實(shí)非常昂貴。64GB版的售價(jià)為999美元，256GB的售價(jià)竟然高達(dá)1,149美元。你會(huì)花這么多錢來買一部智能手機(jī)嗎？即便按兩年分期購買一部iPhone X，你每個(gè)月至少也要支付49.91美元。這樣一部新智能手機(jī)真得物有所值嗎？顯然蘋果是這樣想的。（財(cái)富中文網(wǎng)）

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.
