站长搜索（www.adminso.com）：最强平板：苹果 iPad Air 2全面评测

iPad这个乔布斯时代的系列产品已经发展到了第五个年头，但用户手里的产品却是花样百出，除了第一代以外，后面三代产品都有非常高的使用率，甚至很多人还在用iPad 2。

这种情况在老人和孩子当中较为常见，我们不能说iPad升级乏力，但用户换新的确需要一个理由，而在我使用过刚刚发布的极度瘦身的iPad Air 2和iPad mini 3两款最新产品后，我相信前者是会重新激发老用户的换机热情的。

最轻最薄的iPad，让别的平板怎么活？

有时候传言是挺害人的，例如早早就传出“iPad Air 2”将瘦身至7mm，但实际数字是6.1mm，比上一代7.5mm薄了不是一点半点，相应的重量也缩减到了444g，有人开玩笑说苹果“重新定义了铅笔（源自发布会时的演讲视频）”，但如果一款将近10寸的平板比自家的手机还要薄，的确是有些不可思议。

实际上如果你一路用过几代的iPad产品会发现，iPad 2重量方面不太令人满意，“削边”处理导致握持感也不够舒适，这两点在iPad Air上得到了大幅改进，在此基础上iPad Air 2依然能够继续瘦身18.7%也真是够拼的，拿在手里的感觉比我的iPhone 6还要薄，几乎就只有一个鼠标垫那么厚，或者你可以看一下自己的3.5mm耳机头，iPad Air 2除了屏幕以外的机身部分，基本就是一个标准耳机孔的厚度了。而重量方面我把它放到了随身的单肩背包，老实说如果不是刻意感知的话，你还真不会意识到自己背了一个平板。

这种尺寸与重量上的改变，令人拿在手里感觉愉快，与上一代相比就好像是汽车配置里的豪华版升级到了至尊版――好上加好。不过我担心的是会不会有熊孩子去店里掰弯iPad Air 2，我试了一下，没掰动……

大家都知道变薄是要有代价的，所幸这次不是摄像头突出，而是静音键消失了，尽管我平时都把这个按键自定义为旋转锁定键，但取消掉了倒也影响不大，反正大家在乎的都是尺寸和重量，一个无关紧要的按键就由他去吧。

另外一个显著的变化就是iPad Air 2与iPad mini 3都增加了土豪金的配色，不过并没有金光闪闪的媚俗感，反而算是一种低调的金色了，我个人倒是觉得从审美上压到了银色和灰色，相比来说金色更加耐看一些，特别是与正面的白色外框搭配来说。

整体来说我觉得如果你是iPad二代三代产品的用户，仅凭外观也是你升级的动力了，而如果一年前就买了iPad Air，那么我倒觉得你还是可以克制一下自己的升级欲望的。当然问题也就来了（不是平板技术哪家强，这还算问题吗），其他那些厚得像砖一样的平板还怎么活啊……

指纹解锁，这个可以有

Touch ID出现在两款最新的iPad产品上并不令人意外，至此为止苹果所有的移动设备就全部普及了指纹解锁功能，不仅安全性更佳，也为下一步Apple Pay的推广打下伏笔。

我试验了一下两款产品的Touch ID功能，与iPhone 5s和iPhone 6上面的表现完全一样，这个设置与操作经过两代产品的发展已经是大家所熟悉的了，使用体验很好，解锁基本能达到随心所欲的境界，各个歪七扭八的角度也不在话下――手指头爱出汗的人除外，当然我没有试验一些怪异的部位解锁……

在今年6月WWDC期间，苹果开放了Touch ID功能的第三方应用，不过到现在还没有App出来，所以目前能够做的就是解锁+购买App Store软件，另外一个用处就是，可以从正面看出iPad Air 2的颜色，因为这一代增加了土豪金。

800万像素摄像头，拍照效果最好的一代

终于，iPad家族延续了三年的500万像素摄像头得到了升级，800万像素这个数字看起来与iPhone 6和6 Plus拉平了规格，但实际是这个样子的吗？

首先大家不要迷信数字，尽管都是800万，但iPad Air 2与iPhone 6还是有区别的，最重要的一点就是前者并未使用Focus Pixel技术，而且也没有防抖功能，所以我在同样的暗光环境下拍摄发现，iPad Air 2的对焦速度比iPhone 6稍慢，对焦有点犹豫，不够坚决，当然这是和iPhone 6比，如果与前代iPad Air比试的话真是天壤之别。

我在同样的暗光环境下拍摄了一组照片，发现iPad Air 2的暗部细节明显提高，特别是红绿噪点变得更少，而且精细程度有了更大的提升，画面更加细腻，这是可喜的地方。

当然由于iOS8.1的升级，延时拍摄、慢镜头、对焦/测光分离等功能都加入了进来，后期编辑时也可以调用第三方软件，这都是iPad Air 2在软件功能上得以强化的地方。

整体来说iPad Air 2无疑是拍照效果最好的一代iPad产品，这一短板得到了提升与加强，尽管有些人可能会说用iPad拍照的用户不多，但我总是能看到屡屡举起大平板取景的人，对于一款生产力工具来说，怎能容忍拍照短板呢？

A8X处理器，给一个速度提升的理由

虽然大家都知道iPad Air 2采用了A8X处理器，但苹果并没有公布这颗应该是迄今为止苹果最快处理器的技术规格，而以往在iPad家族上也都曾经采用过“X系列加强版”处理器的做法，例如A5X和A6X，只是A7那一代没有采用这种方法。

对照iPhone6推出时采用的20nm工艺的A8处理器，可以猜测A8X也是保持20nm工艺，而在发布会上苹果宣称A8X的处理器性能CPU比第一代提升了12倍，GPU提升了180倍。

同时外界也普遍认为，A8X在A8处理器20亿晶体管数量的基础上，又增加了10亿晶体管，从而达到惊人的30亿，而这其中绝大部分我们相信都是用在了GPU身上，也就是为了照顾到iPad Air 2的2048×1536的大屏表现，而在这部分着重增强，特别是iOS 8在支持METAL开发工具后，更是将游戏渲染效果拿出来大书特书，因此硬件配置更是要跟上节奏。

我不想说“不服跑个分”之类没有意义的俗话，还是用游戏来说事吧，为了测试iPad Air 2的A8X处理器，我分别安装了《禅境花园》、《无尽之剑》、《真实赛车3》三个比较耗资源的游戏。

《禅境花园》是在今年WWDC上演示过的“游戏”，其实它不能叫做游戏，因为没啥可玩性，但画面效果应该是当下iOS平台上的示范及产品，需要iOS 8+A7以上处理器才能运行，iPad Air 2运行效果相当流程，各个场景切换过渡也极为顺畅，花瓣、蝴蝶、水波、雾气等自然特效生动逼真，如果以后的游戏都是建立在类似这个游戏的METAL平台上开发出来的，那还真是相当期待，只可惜我无法在iPad三代以前的产品上来对比，因为根本跑不起来。

《无尽之剑》和《真实赛车3》是我常玩的两个游戏，基本上也是“炫机”的手段，两款游戏在iPad Air甚至更早的产品上都能跑得起来，但拼的就是载入时间了，我感觉iPad Air 2相比上一代产品，载入时间至少快了一倍以上，也就是等待的时间更短了。

另外一个并未引起多数人注意的细节就是，iPad Air 2的音效相比上一代有所提升，这在玩游戏以及听歌时非常明显，由于没有拆解，因此我们不得而知iPad Air 2外放喇叭的布局以及用料是否有所调整，但底部的外观设计的确是有所变化，就我的听感来说，立体声效果有了明显的增强，并且低音效果也略有提高，我深知觉得相比iPhone 6的外放效果也略好了一点点，毕竟iPad Air 2可以使用更大尺寸的喇叭。

iPad mini 3也是个犹豫的事

实际上我们要承认这一代iPad mini 3的升级并不够大，只是增加了Touch ID以及金色版可供选择，处理器、屏幕等主要部件都没有升级，尺寸没变机身甚至还重了几十克，那么用户该如何选择？

我觉得很多iPad用户都有观望心理，毕竟现在手里已经有产品可用，并不着急升级，除非出现很强的动力，不然旧产品依然可以发挥作用，iPad mini系列就是这样，对于第一代iPad mini的用户来说，我觉得还是可以升级到iPad mini 3的，毕竟一代产品还不是视网膜屏幕呢，而如果已经入手了iPad mini 2那么我建议可以等等看下一代产品。

总结：继续纠结屏幕尺寸

就像iPhone 6和6 Plus发布之后大多人都会纠结于尺寸那样，iPad Air 2与iPad mini 3的用户也会陷入这个两难的选择。乍看起来似乎iPad mini 3升级变化不大，如果二选一的话轻薄与性能遥遥领先的iPad Air 2完胜，但实际上并不是这么简单的。

iPad Air 2的目标用户是强调移动生产力的那一群人，在iOS 8发布会之后，iWork三件套通过Hand Off以及iCloud Drive等工具与Mac协作得更好，所以通过各种配件你真的可以拿来实现移动办公；但iPad mini 3则不然，它更多的依然是阅读或是消遣娱乐的工具，也就是拿来消费内容的，而不是产生内容的，这个讨论就像iPad诞生之初那样明显。

对于iPad Air 2来说，我感觉这是该家族诞生以来最酷的一代产品，革新性比较大，重新燃起了用户的热情，而且令iOS设备的协同性更好了。当然对于用户来说，更薄、更快、更安全，拍照效果更好，我想这就足够了。

尽管今年iPad mini 3并未有太多的升级，只是增加了Touch ID、金色版，但所有人都会期待一件事，那就是iPad Air 2上的革新用不了多久就会出现在下一代iPad mini身上，我想那才是真正最酷的一代小尺寸平板。
