->很多所谓的IE问题不是单纯的IE问题，而是系统的问题。(不是微软才有系统问题)
It is not 单纯的IE问题, but a IE design problems - binding is the culprit (or we can say Windows design problems, but IE is an application on Windows). Let's simplify it. If there is no binding, IE can be much more free from the security troubles and protects Windows better. Binding is two side blade.
->用FF/Opera不解决系统的问题。就这么简单。
That's true. Both behaves excelent on different platforms. They have less security problems on OS.
->对同一个用户而言，如果你有心去装FF等，你也可以用那些时间/精力配好IE并更新系统，补上漏洞。后者才是关键。
Do you mean it takes the same "时间/精力配好IE并更新系统，补上漏洞" as that to install FF? If so, can you please give us your value results?
->FF的很多功能在基於IE的外壳上都可以实现，而且这些外壳有很多FF没有的功能。而这些外壳往往比FF要小得多。
Do you know how many customers know how to use 外壳? Is the 外壳 the browser or IE?
