请把下面的汉语翻译成英文：
从各位高管的意见中明显可以得出这样的结论：不管是苹果(Apple)的iPhone还是罗尔斯?罗伊斯(Rolls-Royce)的Trent飞机引擎，真正创造利润的不是组装产品的基础环节，而是服务、品牌、设计和售后。
英语原文：
It became apparent listening to various executives that whether it is Apple iPhones or Rolls-Royce Trent aero engines, the real profit is not made in the basic assembly of goods. The margins are in servicing, brands, design and after-sales.
