科技资讯:苹果的全新iPad 六大新特性  

APPLE used to be coy about its uping products. The press invitation unveiling of its latest iPad tablet puter depicted a finger pressing a high-resolution touch-screen with the label: "We have something you really have to see. And touch." In the event
perhaps the biggest surprise to e out of the presentation by Apple's boss
Tim Cook
was that the pany is calling the device just "iPad" and not
as had been expected "iPad 3".
苹果总爱对自己的新产品严格保密。在新iPad平板电脑发布会上，有一只手指按在一块高分辨率的触摸屏上，旁边还注明着这样一段话：“我们要让你真正去看，去摸”。或许后来真正让人惊讶的是苹果CEO蒂姆•库克仅仅把新产品称为“ipad”，而不是人们预期的“iPad3”。
To be sure
the svelte gizmo sports a plethora of improvements over its numbered predecessor
the iPad 2. Its new "Retina Display" boasts four times as many pixels
close to the limit of human perception
and its four-core graphics processor makes the experience of what was already the smoothest tablet smoother still. Lower-resolution apps
such as those developed for earlier iPads
still look sharp on the new device (each old pixel is translated into four new ones)
something rival Android devices
which e in a variety of shapes and sizes
struggle with. It also has a better
5-megapixel camera. But these changes had been much anticipated in the blogosphere's techier quarters.
的确，这个纤薄的小玩意比起前辈iPad2有着大量的改进。比如它的“视网膜屏幕”，声称其像素是以往的4倍，已接近人类视觉极限，而四核图形处理器将为平板带来最流畅的操作体验。即使是为前代ipad设计的那些低分辨应用程序在新产品上画质表现依旧细腻（每个像素被转换成四个），这对于各式各样的安卓设备来说这是一大优势，此外，新iPad还采用了更强大的500万像素摄像头。但是，这些改进早已被博客世界的技术板块预测到了。
There was a bit more uncertainty about fourth-generation (4G) mobile connectivity. Here
Apple seems to have dealt with several bugbears of Long Term Evolution (LTE)
an increasingly ubiquitous 4G standard capable of faster download rates and more consistent reception. LTE smartphones are often ungainly due to the hefty electronics needed to support it. Apple
famous for its sleek design
could have none of that. The iPad's already ample battery has been eaked so that it matches the ten hours in 3G mode of older models
and lasts fully nine hours with LTE on
while feeding a power-hungrier display. That marks a significant improvement over the smaller LTE devices currently on the market
some of which last only a few hours.
有一点不确定就是新iPad在4G移动数据的连通能力上，苹果似乎在LTE（Long Term Evolution长期演进）上遇到了一点小麻烦，LTE作为4G标准已经初具规模并且在上传和下载速度上都有着良好的表现。但由于LTE芯片比较庞大，所以LTE智能手机常常显得很笨拙，但这当然不会出现在以时尚设计著称的苹果身上。新iPad还配备了一块强劲的电池，这不仅使它在满足更加耗电的屏幕同时，还能在3G模式下坚持使用10小时（达到了前代的标准），即使在4G模式下也能坚持9小时。这在当前LTE设备市场算得上一个重大的突破，因为同类产品只能使用很短时间。
Apple used its buying power and dominant position in the tablet market to hit petitors like Microsoft
whose partners are preparing to launch an array of Windows 8 Metro slates later this year. The new iPad prices haven't budged. They start at $499 for a 16-gigabyte Wi-Fi only unit and finish at $829 for a 4G tablet with 64 gigabytes of flash storage. At the same time
Apple is keeping the older iPad 2 on the market for $399 with Wi-Fi and $529 with 3G.
苹果利用其粉丝的购买力和其在平板市场的主导地位给了竞争对手强力一击，比如微软，后者准备在年底与合作伙伴推出一系列预装Windows 8 Metro界面的平板电脑。此外，新iPad的价格并没有超过上一代，最低是16G的 Wifi版，499美元起，最高的是64G的4G版，829美元。同时苹果还调低了iPad2的价格，Wifi版399美元，3G版529美元。
Other firms had already been hard-pressed to meet Apple's price
battery life and hardware features
let alone its swish operating system
copious media catalogues and the inter's biggest app store. With an upgrade at the top of the line and a drop in price for the current bestselling model
the iPad is unlikely to be dethroned any time soon. Apple has every reason to blow its own trumpet.
苹果产品的价格、电池续航时间还有硬件，更不用说其华丽的操作系统、丰富的多媒体资料和最大的网上应用商店，这些都给了其他公司很大的压力。在升级高端产品线的同时调低畅销产品的价格，新iPad在很长一段时间内都不会过时，苹果的确有他骄傲的资本。
