微软发布了IE8和其他浏览器的功能对比图。当然微软不敢放出性能对比的。
不过这个功能对比图也实在够YY的。

我们简单来分析看看。
Windows Internet Explorer 8_ Get the facts.jpg  
表格中只对比图上之对比了三种浏览器。。。safari去哪里了?Opera去哪里了?
我们再一条一条地分析。
Security: Internet Explorer 8 takes the cake with better phishing and malware protection, as well as protection from emerging threats.
安全性这个不否认,IE的确做得不错。
Privacy: InPrivate Browsing and InPrivate Filtering help Internet Explorer 8 claim privacy victory.
我记得最早有隐私模式的并不是IE把。safari和Chrome很早就有该功能了。
Ease of Use: Features like Accelerators, Web Slices and Visual Search Suggestions make Internet Explorer 8 easiest to use.
其实我觉得加速器挺烦的。用户体验因人而异
Web Standards: It's a tie. Internet Explorer 8 passes more of the World Wide Web Consortium's CSS 2.1 test cases than any other browser, but Firefox 3 has more support for some evolving standards.
IE说他符合了web标准,其他浏览器笑了。不过IE8还是中肯得说,的确做了很多努力。
Developer Tools: Of course Internet Explorer 8 wins this one. There's no need to install tools separately, and it offers better features like JavaScript profiling.
好意思说么?或许这是没把safari放进来的原因,如果把safari也对比以下,这条“优势”估计又没法写了。
Reliability: Only Internet Explorer 8 has both tab isolation and crash recovery features; Firefox and Chrome have one or the other.
这个得益于多进程,但是多进程的浏览最早也是Chrome带来的先进理念。
Customizability: Sure, Firefox may win in sheer number of add-ons, but many of the customizations you'd want to download for Firefox are already a part of Internet Explorer 8 – right out of the box.
又爱又恨的ActiveX,至今留在 navigator.plugins 为空白就是最好的不标准证明。(标准的控件安装后,是多浏览器共享的,记得我们的flash安装么?)
Compatibility: Internet Explorer 8 is more compatible with more sites on the Internet than any other browser.
个人观点,这个其实挺贬义IE的。的确,IE8能够兼容最多的站点。那是因为IE埋下了不兼容的种子,只有自己兼容了。而且IE8把兼容和不兼容的站点都统统兼容了,也当之无愧得说more compatible with more sites…但是也暗示着IE坎坷的未来。一个如此庞大的兼容系统。如何能够更好得维护和提升性能?
Manageability: Neither Firefox nor Chrome provide guidance or enterprise tools. That's just not nice.
这个IE做得很好,提供了不少给企业定制的工具。
performance: Knowing the top speed of a car doesn't tell you how fast you can drive in rush hour. To actually see the difference in page loads between all three browsers, you need slow-motion video. This one’s also a tie.
这个曾经微软也过一份页面加载完成时间的对比的表格。表格中显示,IE加载完成时间很快哟。不过这个远远不够,很多方面的性能测试,IE都是落败的。而且这个表格的测试标准也没有说法(页面加载完成时间通常有很多因素决定),不排除自己YY的嫌疑。
不过,看到这个张表格,实在为IE的前景堪忧。
