真是学到的东西不多，如果是让我花1000大元，打死也不去！
还有一节课是J2ee与.net的比较，很可笑，都是在win下进行的！多公平啊！！！！
现在M$企图使用java的pet store作对比，实际上Pet store是个学习演示的例子，并没有针对性能优化，pet store向我们展示了各种J2EE模式的使用，这肯定会牺牲一些性能。
看看现在做金融的，证券的，不都是java的天下？
Microsoft has published a comparison of creating a Web Service using Microsoft® Visual Studio.NET and IBM WebSphere® software.
Although we appreciate Microsoft's recognition that IBM and its WebSphere software are leaders when it comes to delivering Web Services capabilities, we'd like to note some inconsistencies in their comparison. Their comparison involved an inconsistent use of alpha, beta and "Generally Available" technologies, resulting in a comparison of unlike items. We find this misleading. Shouldn't you compare "like" items? Missing from their comparison is freedom of choice. Microsoft seems to have forgotten that freedom of choice is important to you. After all, the Internet and Java are all about choice - choice of hardware, choice of Operating System, choice of language, and choice of development platform - which translates into business flexibility. It's this business flexibility that let's you leverage current and ongoing investments, so you won't find yourself in the position of having to rebuild your entire system.
What's clear in the comparison below is that Microsoft tools fail to run on leading industry products and platforms, like Java™, J2EE®, Sun® Microsystems Solaris, IBM AIX®, IBM i-series® and IBM z-series®. We can all quote benchmarks, but they don't tell the whole story. Because it's really about choice and integration, proprietary, and single vendor versus open and multi-vendor.

有道理：）
我会追随你的
那里都是微软
毫无疑问，从代码量和开发周期上来说， MS 是有绝对优势的。
Java 开发的门槛相对还是比较高的，熟悉J2EE要花一定的时间，会融会贯通，又要花一段时间。也难怪 MS 在国内有这么多的拥护者。
看看国外，正规公司的 IT，大多使用 MS 的方案，因为它简单，能在最短的时间内满足客户的需求。
我不喜欢 MS 的东西，但是，我不得不说，MS 实际上还是很伟大的。
为什么这样说? 因为每个人的需求不同。
以程序员的角度来看系统，我最喜欢的就是以前写在 DOS 下写 ASM 的时候，好像计算机的一切就展现在你的面前，你可以随意控制它。做为一个程序员，希望能对系统获得更大的控制权。
以应用人员的角度来看，做 Photoshop 或 3DMax 的人，他们不希望花好多的时间去学习一些 OS 的特殊命令。 要不然像 Unix 下的 GIMP 这样功能强大，而且还 Free 的软件为什么这么少人用? 因为应用人员只想 focus 到 Design 上。
MS 实际上正是在做这样的人的生意。我们可以看到，在国外的 Research & EDU org 里很少有人用 Windows, 大家都觉得它是个垃圾。对资料不安全。但是对于要娱乐，对于 focus 到与计算机没有什么关系的方面的人来说，Windows 就是最好的!
所以，MS 有它的市场!
