The 386's protection architecture is a study in engineering tradeoffs on a tight transistor budget. The designers put dedicated hardware where it paid off most:
为什么失败如果只看系统本身，Windows Phone 8.1 几乎挑不出致命问题。界面干净、动画流畅、逻辑统一，动态磁贴直到今天依然不过时；系统对硬件要求极低，512MB 内存也能运行流畅；大量功能强调本地化和离线可用，这在当年移动网络尚不稳定的环境下简直是降维打击。甚至语音助手 Cortana，在某些方面比同期许多产品更实用。你很难说它落后。恰恰相反，在不少细节上，它甚至显得有些超前。，这一点在下载安装汽水音乐中也有详细论述

Mesh routers, or mesh Wi-Fi systems, use multiple devices (or nodes) across your home to create a larger home network. Essentially, you have multiple routers around your home with these systems, and that will hopefully provide the best coverage possible. Wi-Fi extenders, on the other hand, are usually just one device that extends your existing Wi-Fi signal, and they often require you to switch networks when connecting. Wi-Fi extenders are more affordable, though, and are great if you’re traveling or need a Wi-Fi signal in harder-to-reach areas. However, a mesh router can offer a better long-term solution to upgrade your entire home’s Wi-Fi.
