Actually, Ai Yue is not very sensitive to Mac World, after all, it's just Apple showing off alone. Relatively speaking, CES is the focus of Ai Yue's attention. Unfortunately, the speech by Microsoft's former president, Bill Gates, at CES did not resonate with Ai Yue. On the contrary, Steve Jobs brought more than just shock to Ai Yue. So, in this article, I want to first point out that Ai Yue's English level is only CET4, but Steve Jobs is indeed a master of public speaking, with a moderate pace. Even if some sentences are not understood, their meaning can be inferred from the context. Here, I want to mention a small story: it is said that before Steve Jobs' speech, many Google employees were waiting outside the hall for the start of Steve Jobs' presentation. Why? Because in their eyes, "a master's speech cannot be missed." So, Ai Yue didn't miss it either and specially downloaded the Mac World 2008 Steve Jobs Keynote, in MP4 format, officially produced and available for download on the official Apple website. The clarity is incomparably better than that of Bill Gates' keynote provided by Microsoft, even compared to the high-quality video offered by Microsoft. Well, now that the trivial talk is over, let's talk about the content of Steve Jobs' speech. The entire speech was divided into four parts, with Steve Jobs inviting two senior executives to take the stage to show off, along with some of Apple's own high-definition advertisements, and ending with a piano performance.
