操作系统对MacBook Air轻薄特性和被动无风扇散热的贡献
如果你还记得乔布斯在2007年的iPhone发布会上，他引用了艾伦·凯的话，表示那些认真对待软件的公司应该自己制造硬件。如今我们看到的MacBook既纤薄又无风扇，采用被动冷却技术，这确实是一项工程壮举。
问题是，这其中有多少是由于操作系统的创新，比如代码优化、多线程架构的新颖之处等，多少是纯粹的硬件工程，比如在狭小空间内紧凑地安置大量组件？无风扇的被动冷却是否在某种程度上依赖于操作系统——即它以某种方式运行，使得机器的温度始终不会超过某个阈值，因此不需要风扇？
MacBook的用户常常说，苹果设备之所以出色，是因为硬件和软件是“交织在一起的”。具体来说，这种交织是怎样实现的呢？

If you recall Jobs' iPhone keynote in 2007 - he quoted Alan Kay saying that companies who are serious about software should make their own hardware. As we see MacBooks today are slim, fanless, passively cooled. That is indeed an engineering feat.<p>Question - how much of it is due to innovations in the OS - like optimizing code, multithreading architecture novelties, etc., and how much of it is pure hardware engineering like shoehorning lots of components in cramped space? Does the passive cooling without fan dependent on the OS in any way - that it runs in such a way that the machine is never heated above a certain threshold and hence fan is not required?<p>MacBook folks often say that Apple devices are col because the hardware and software are "intertwined". How exactly?
