Steve Jobs谈Android Tablets，句句切中要害啊！

　　其次，我想谈谈将在未来几个月内“蜂拥而至”的大量平板电脑。

　　第一，似乎只有为数不多的几款可靠的产品，而不是“蜂拥而至”。

　　第二，几乎所有这些产品都使用7英寸的屏幕，而不是iPad所使用的10英寸屏幕。让我们从这里开始。

　　有人或许认为，与10英寸的屏幕相比，7英寸的屏幕将提供70%的益处，这是一种非常自然的想法。但不幸的是，事实远非如此。屏幕尺寸衡量的是对角线长度，所以7英寸屏幕只有10英寸屏幕的45%。没错，你没听错：只有45%。

　　如果你使用iPad的纵向视图，在中间画一条水平线，那么7英寸的平板电脑屏幕还不如iPad下面的那一半大。在我们看来，这种尺寸不足以创建优秀的平板电脑应用。

　　尽管可以通过提升屏幕分辨率来弥补部分差异，但是仍然于事无补，除非你的平板电脑还配备一张砂纸，让你可以将手指头打磨成现有尺寸的四分之一。

　　多年以来，苹果已经对用户界面做过大量的用户测试，而且我们真正理解这一问题。的确存在一个明显的界限，一旦小于这一界限，用户就无法在触摸屏上舒适地用手指完成点击、移动或掐捏的动作。这正是我们认为10英寸是创造优秀的平板电脑应用的最小尺寸的重要原因之一。

　　第三，所有的平板电脑用户同时也是智能手机用户。没有一款平板电脑的移动性能可以与智能手机媲美，后者可以被轻松放入口袋或钱包，而且在人群中 使用时，不会太显眼。考虑到所有的平板电脑用户的口袋里应该已经有了一款智能手机，牺牲珍贵的屏幕尺寸，让平板电脑可以放入口袋显然是错误的权衡。

　　7英寸的平板电脑是一种四不像：与智能手机较量个头太大，与iPad竞争又个头太小。

　　第四，几乎所有这些平板电脑都使用Android系统，但是就连谷歌也曾告知平板电脑厂商，不要将他们现有的版本(Froyo)用于平板电脑， 而应该等待明年专门针对平板电脑的版本推出。当你的软件供应商告诉你不要将他们的软件用于平板电脑时，意味着什么？当你不顾劝阻而一意孤行时，又会意味着 什么？

　　第五，苹果应用商店中目前已经拥有3.5万款iPad应用。而这些新款平板电脑的应用几乎为零。

　　第六，也是最后一条，我们的潜在竞争对手在定价方面很难接近iPad的水平，尽管他们采用了尺寸小得多、价格便宜得多的屏幕。iPad整合了我 们在创建高价值产品过程中所学到的一切，包括iPhone、iPod和Mac。我们开发了自己的A4芯片、自己的软件、自己的电池、自己的附件，一切都是 我们自己的。而最终这款不可思议的产品却以非常优惠的价格出售。

　　这一点可以在我们竞争对手的定价中体现出来，他们提供的功能更少，但价格却更高。以上这些原因正是我们认为当前那些7英寸的平板电脑将会“见光 死”的原因。这些厂商将会因为屏幕过小而吸取惨痛的教训。他们明年会增大尺寸，但却会因此抛弃那些过早加入7英寸阵营的消费者和开发者。听起来今后的情况 会很有趣。

　　iPad对笔记本销量的影响

　　iPad无疑将影响笔记本电脑的销量。这只是时间的问题。我相信未来几年iPad将会有进一步的开发和进展。但我们现在已经看到教育用户对 iPad拥有很高的兴趣。令我惊讶的是，企业用户也对iPad很感兴趣。我们没有真正在企业领域推广iPad。我每天都跟各种企业员工接触，很多人都在使 用iPad。从董事会成员到护士、医生和医院，以及中小企业，很多人都在使用iPad。

　　因此随着时间的流逝，我相信我们已经抓住了一个重要机遇。这是一个新的计算模式，而且我们已经拥有几千万熟练使用iPhone的用户。平板电脑 将融入到生活的各个方面，包括个人生活、教育和企业等。因此我认为平板电脑的用途是很广泛的，潜力非常大。或许还有一些人会争论时机的问题，但我认为没有 人会否认平板电脑的时代即将来临。

Second, I'd like to comment on the avalanche of Tablets poised to enter the market in the coming months. First, it appears to be just a handful of credible entrants, not exactly an avalanche. Second, almost all of them use seven-inch screens as compared to iPad's near 10-inch screen. Let's start there. One naturally thinks that a seven-inch screen would offer 70% of the benefits of a 10-inch screen. Unfortunately, this is far from the truth. The screen measurements are diagonal, so that a seven-inch screen is only 45% as large as iPad's 10-inch screen. You heard me right; just 45% as large.

"If you take an iPad and hold it upright in portrait view and draw an imaginary horizontal line halfway down the screen, the screens on the seven-inch tablets are a bit smaller than the bottom half of the iPad display. This size isn't sufficient to create great tablet apps in our opinion.

"Well, one could increase the resolution of the display to make up for some of the difference. It is meaningless, unless your tablet also includes sandpaper, so that the user can sand down their fingers to around one quarter of the present size. Apple's done extensive user-testing on touch interfaces over many years, and we really understand this stuff. There are clear limits of how close you can physically place elements on a touch screen before users cannot reliably tap, flick or pinch them. This is one of the key reasons we think the 10-inch screen size is the minimum size required to create great tablet apps.

"Third, every tablet user is also a smartphone user. No tablet can compete with the mobility of a smartphone, its ease of fitting into your pocket or purse, its unobtrusiveness when used in a crowd. Given that all tablet users will already have a smartphone in their pockets, giving up precious display area to fit a tablet in our pockets is clearly the wrong tradeoff. The seven-inch tablets are tweeners, too big to compete with a smartphone and too small to compete with an iPad.

"Fourth, almost all of these new tablets use Android software, but even Google is telling the tablet manufacturers not to use their current release, Froyo, for tablets, and to wait for a special tablet release next year. What does it mean when your software suppliers says not to use their software in your tablet? And what does it mean when you ignore them and use it anyway?

"Fifth, iPad now has over 35,000 apps on the App Store. This new crop of tablets will have near zero.

"And sixth and last, our potential competitors are having a tough time coming close to iPad's pricing, even with their far smaller, far less expensive screens. The iPad incorporates everything we have learnt about building high value products from iPhones, iPods and Macs. We create our own A4 chip, our own software, our own battery chemistry, our own enclosure, our own everything. And this results in an incredible product at a great price. The proof of this will be in the pricing of our competitor's products which will likely offer less for more.

"These are among the reasons we think the current crop of seven-inch tablets are going to be DOA, Dead on Arrival. Their manufacturers will learn the painful lesson that their tablets are too small and increase the size next year, thereby abandoning both customers and developers who jumped on the seven-inch bandwagon with an orphan product. Sounds like lots of fun ahead.
