以下摘自 Apple hot news。
大意，“我们从Mac OS X开发部gate找了一些人来开发iPhone，所以Mac OS X延期——为了保证产品质量。”

Apple Statement
iPhone has already passed several of its required certification tests and is on schedule to ship in late June as planned. We can’t wait until customers get their hands (and fingers) on it and experience what a revolutionary and magical product it is. However, iPhone contains the most sophisticated software ever shipped on a mobile device, and finishing it on time has not come without a price — we had to borrow some key software engineering and QA resources from our Mac OS X team, and as a result we will not be able to release Leopard at our Worldwide Developers Conference in early June as planned. While Leopard's features will be complete by then, we cannot deliver the quality release that we and our customers expect from us. We now plan to show our developers a near final version of Leopard at the conference, give them a beta copy to take home so they can do their final testing, and ship Leopard in October. We think it will be well worth the wait. Life often presents tradeoffs, and in this case we're sure we've made the right ones. [Apr 12, 2007]

苹果公司声明
iPhone已经通过了几项必需的认证测试并会在六月下旬如期出货。我们已迫不及待地想让用户的手（手指）放在iPhone上，亲身体验这梦幻般的革新性产品。然而，iPhone内置的软件比市面上任何移动设备都要复杂。为了完成这样一个艰巨任务，我们不得不付出代价——我们从Mac OS X团队中抽调了几名核心软件工程师和QA Resources。这样的话，Leopard便不能按计划在六月上旬的WWDC上发布了。到那时Leopard的特性和功能将会全部呈现，但我们和用户所期待的高品质版本却无法在那时发布。我们现在计划在WWDC大会上能给开发者一份最终测试版。开发者可以把这份测试版带回家，做最后的测试。Leopard会[屏蔽]开始出货。我们认为Leopard值得大家的期待。生活经常需要我们做个取舍，我们认为这个抉择是正确的。

哈哈
苹果还真是坦率

生活经常需要我们做个取舍，我们认为这个抉择是正确的。

现在已经不是Apple Computer Inc.了...

是啊，已经是Apple Inc.了，所以要为iPhone作出取舍了～～～
希望两个都是好产品

支持 一个 不过 我想 iphone 不会在中国适用的吧

会不会在以后的MAC新机上面装leopard呢？
