科技前沿:谷歌新款Nexus7 平价平板之王‘天博tb·综合体育’

Does size still matter? Just a year ago, Google introduced its Nexus 7, a mini tablet for $199 that posed a real challenge to Apples bigger, pricier iPad. Three months later, Apple retaliated with its own small tablet, the iPad Mini, though its $329 price wasnt, well, mini enough for some. 尺寸依然最重要吗？就在一年前，谷歌(Google)发售了Nexus 7。这款售价为199美元的迷你平板电脑，对苹果公司(Apple)屏幕更大、价格更高的iPad包含了确实的威胁。

三个月后，苹果发售了小型平板电脑iPad Mini不予开火，虽然329美元的价格对于很多人来说并不“迷你”。Now, a year after the introduction of the first Nexus 7, Google has unveiled a revamped version of its mini tablet with better features and a slightly bigger $229 price tag. 如今，第一代Nexus 7发售一年之后，谷歌公布了它的新版本。这款平板配有了更加强劲的功能，价格小幅下跌至229美元。Starting July 30, this new Nexus 7 is available in a dozen retail outlets including Best Buy, Wal-Mart and Amazon. 这款全新的Nexus 7从7月30日开始指定各大销售平台，还包括百思买(Best Buy)、沃尔玛(Wal-Mart)和亚马逊(Amazon)。

I tested it for the past week and found myself drawn to this sturdy, elegant, responsive device from a company once known primarily for its search prowess. 经过一周的测试，我发现自己深深爱上了这款牢固、高雅、反应灵敏的设备；而它的生产商过去主要是以其强劲的搜寻业务闻名。The most notable difference between this new Nexus 7 and the iPad Mini is screen quality: The Nexus has a resolution of 1920 x 1200 with 323 pixels per inch, and the iPad Minis screen resolution is just 1024 x 768 and 163 pixels per inch. It is also slightly lighter than its Apple rival. 新款Nexus 7和iPad Mini仅次于的差异在于屏幕：新款Nexus的分辨率高达1920 x 1200，每英寸323像素；而iPad Mini的屏幕分辨率仅有为1024 x 768，每英寸163像素。并且Nexus 7也更加轻巧。

So whats not to like about the new Nexus 7? For one thing, its 7-inch screen isnt as big as the nearly 8-inch iPad Minis. While an inch of difference isnt remarkable, smartphone screens are growing to over 5 inches, making the Nexus 7 look more like one of those than a tablet. 那么新款Nexus 7有什么劣势呢？首先，七英寸的屏幕比起iPad Mini相似八英寸的屏幕要小一些。尽管一英寸的差异并不明显，不过很多智能手机的屏幕都早已多达五英寸了，这竟然Nexus 7看上去更加像一部手机而不是平板电脑。Another drawback: In my test, the new Nexus 7s battery life was underwhelming. Compared with the same battery test of the iPad Mini and first Nexus 7, it fell short at just six hours; the others clocked in at 10 hours and 27 minutes and 10 hours and 44 minutes, respectively. Google claims the battery life can last over nine hours, but the company tests it in Airplane mode (Internet connection off), with screen brightness set to 44% while playing video. I keep Wi-Fi on in the background and screen brightness at 75% while playing video. 其次，在我的测试中，新款Nexus 7电池的续航能力较为肤浅。

在完全相同的测试条件下，iPad Mini的电量可以保持10小时27分钟，第一代Nexus 7为10小时44分钟，而新款Nexus 7的续航时间仅有六个小时。谷歌声称其新款Nexus 7的电池可以保持多达九个小时，但它们的测试是在飞行中模式（没网络连接）、屏幕亮度44%的设置下播出视频。而我是仍然进着无线网络并把亮度调往75%来播出视频的。

This new mini tablet comes in two sizes that are Wi-Fi-only: a $229 16-gigabyte model and a $269 32-gigabyte model. A version with a built-in LTE Internet connection on Verizon, ATT or T-Mobile will be available in coming weeks for $349 with 32 gigabytes. Meanwhile, Apples iPad Mini is available in three flavors each of Wi-Fi-only and LTE: 16-, 32- and 64-gigabyte models ranging in price from $329 to $659. 这款全新迷你平板电脑有两种版本可选：16G的价格229美元，32G的售价269美元，皆为Wi-Fi版本。而内置Verizon、AT＆T或T-Mobile公司LTE 网络的型号，将不会在未来的数周内发售，内存32G，售价为349美元。与之比起，苹果的iPad Mini有Wi-Fi和LTE两种型号，根据内存（16G、32G和64 G）的有所不同，价格从329美元至659美元平均。

The new Nexus 7 runs Android 4.3, the latest iteration of Googles Jelly Bean mobile operating system. While not a major upgrade from the last Jelly Bean release in October, it does add a few new features. 新款Nexus 7的操作系统是谷歌公司“果冻豆(Jelly Bean)”操作系统的近期版本──安卓(Android) 4.3。虽然相对于去年十月公布的“果冻豆”系统并远比一次主要升级，可4.3版本依然加添了一些新的特色。One notable extra is Restricted Profiles. Rather than simply giving you the ability to create multiple user accounts for one tablet, Restricted Profiles allow user accounts with preset restrictions on access to apps and content. I tested this by creating a Restricted Profile named Pretend Kiddo in Settings, Users, Add User or Profile. I then went down a list of my devices apps and switched access on or off, according to what I wanted Pretend Kiddo to be able to access. Certain apps in this list clearly say This app can access your accounts, so you know what youre turning on or off. 一个特色是“容许档案(Restricted Profiles)”。

不同于全然地在同一部平板电脑上创办多个账号，“容许档案”需要让使用者提早设置一些应用程序和内容的采访容许。为了测试这项功能，我在“设置-用户-加到用户或档案”里，创办了一个叫作“假装小孩(Pretend Kiddo)”的账号。

然后我看了一遍设备上的应用程序列表，并根据我想要让“假装小孩”这个账号需要指定的明确程序来设置指定容许。一些应用程序明晰标明了“这款应用程序需要指定您的账号”，因此，你可以很更容易地告诉到底应当要关上还是开动它。Creating a Restricted Profile requires that the primary tablet owner use a lockscreen, so that other users without full access cant get to everything else. In addition to limiting what the Restricted Profile can access, specific app settings, such as in-app purchases and age restrictions, can also be tweaked. 创立一个“容许档案”必须主账户用于锁住屏程序，这样其他没原始权限的用户就无法登入某些程序。

除了设置“容许档案”的指定权限，个别应用程序的设置，例如程序内出售和年龄容许也可以调整。Another new Android feature allows users to play games against friends while keeping track of their achievements using Google Play Games. This is a lot like Game Center on Apples iOS. 另外一个新的特色就是通过谷歌游戏中心(Google Play Games)，用户可以和朋友们在游戏中对付并记录成绩。这和苹果iOS系统的游戏中心(Game Center)功能类似于。The Nexus 7 also caught up to the iPad Mini in cameras: It now has a built-in rear-facing camera, unlike its predecessor, which only had a front-facing one. Both iPad Mini and new Nexus 7 cameras have the same megapixel counts: 5 megapixels on the rear-facing camera and 1.2 megapixels on the front-facing one. Neither device has a built-in flash. Nexus 7摄像机功能和iPad Mini非常：它的上一代只有前置摄像头，而新款则配有了一枚后置摄像头。

像素也和iPad Mini完全相同：500万像素后置摄像头和120万像素的前置摄像头。两种设备都没内置闪光灯。

I snapped photos both indoors and outside in the natural light, and found the outdoor images looked better, though the inside ones were adequate. 在自然光情况下，我分别摄制了室内和室外照片，室外照片看起来更佳，但室内的也不劣。I downloaded and watched movies and TV shows on the Nexus 7, admiring its impressively sharp, colorful -- albeit smallish -- screen, which I usually kept in landscape view. Built-in surround-sound speakers placed on both ends of the tablet emulated a six-speaker system, giving it a rich tone. 我用新款Nexus 7iTunes并观赏了电影和电视节目，对它光学明晰、色彩艳丽──虽然有点小──的屏幕印象深刻印象，我一般来说维持在纵向视图状态。

内置在平板电脑两端的环绕声扬声器仿效了六声道系统，彰显了这部机器圆润的音质。At only 0.64 of a pound, this tablet was lightweight enough to hold for long periods without causing my arm to ache. I also found it easy to prop up on kitchen counters and coffee tables because its back and sides arent slippery. 这款平板仅有轻0.64磅（约合0.29千克），因此即使长时间手执这款平板电脑，我的胳膊也会实在酸痛。由于它背面以及四周的尖面设计，我找到把它架在厨房台面或者咖啡桌上也很便利。

Googles new Nexus 7 has a lot to offer, if youre looking for a tiny tablet that packs a punch. If youre used to a larger tablet screen, its 7-inch screen size might bug you. But for many people, it will make on-the-go gaming, video watching and reading a delightfully portable experience. 如果你想要应从一台兼备诸多功能的小型平板，谷歌全新的Nexus 7能符合你的市场需求。可如果你用惯了大屏幕的平板电脑，有可能就不会不习惯Nexus 7的七英寸屏幕。但对于许多人来说，Nexus 7依然能为游戏、观赏视频以及读者获取一个舒适度便利的体验。
