Now, five years ago today, iPhone users began to download apps. 五年前的今天，iPhone 的使用者開始下載應用程式。
It might not seem like much, but the opening of the App Store, it was a milestone, turning handsets from simply being phones into the handheld computers they are today. 那看起來也許不怎麼樣，但 App Store 的啟用可是個里程碑，把手機從單純當作電話變成如今的掌上型電腦。
Now, first, let's remind you what the iPhone was like when it came out back in 2007. 首先，讓我們來提醒各位 iPhone 以前在二○○七年問世時是什麼樣子。
No Facebook, no Angry Birds, no Skype, just the basic apps that came with the phone. 沒有臉書，沒有憤怒鳥，沒有 Skype，只有電話搭載的基本應用程式。
Now, the App Store allowed you to change what your device could do. 然後 App Store 讓你可以改變工具的功能。
And suddenly your phone wasn't just a phone. It was also a piano, it was a game console, or even a comic book. 突然間你的電話不只是電話了。它也是鋼琴，也是遊戲機，或甚至漫畫書。
There are now 850,000 apps on Apple's App Store alone. 現在光是蘋果公司的 App Store 就有八十五萬個應用程式。
And when you combine that with similar services from Google, BlackBerry, Microsoft and more, 如果把那加上谷歌、黑莓、微軟等等類似的服務，
Gartner says all of these stores will generate $25 billion in sales this year. 顧能顧問公司表示，全部這些商店今年將產生二百五十億美元的銷售額。
Now, that dwarfs the entire music industry, which made just $16 billion last year. 這讓去年僅有一百六十億美元的整個音樂產業相形見絀。
And the irony is that none of this would exist if Steve Jobs had his way. 諷刺的是，如果照賈伯斯的意思行事，這一切都不會存在。
Now, the late Apple CEO's biography says that he initially resisted allowing other people to make apps. 這位已故蘋果公司執行長的傳記提到，原本他抗拒讓別人製作應用程式。
He didn't want outsiders to create applications for the iPhone that could mess it up, infect it with viruses or pollute its integrity 他不要外人創造 iPhone 的應用程式，因為可能會把 iPhone 弄亂、感染病毒或有損其完整性
-- proof that Steve Jobs wasn't always right. ——結果證明賈伯斯並非永遠是對的。
