我还远没有资格做评测，CentOS Debian Fedora FreeBSD Ubuntu 里，除了用过 Fedora，其他的都没试用过。还有一些 linux distribution 有些近期不够活跃，有些在开源路线上不够明朗，对从零学起的用户来说，还是不用考虑把它们也加进 shortlist，就这些主流的 linux distribution 都已很让人困惑，该怎么选择？
总的来说，选择谁都没有错，殊途同归。但可能这样的回答不会让人满意，那么根据我的研究结果，我用最短的词语来概括 CentOS Debian Fedora FreeBSD Ubuntu 特点，希望有助大家选择。
Yesterday I received an newsletter from ebuyer promoting an Extra Value PC at under £200. I particularly like the point no OS comes with this PC. However, the reason for not buying was its 32-bit CPU. I definitely want my next generation PC is 64-bit.
I discarded that newsletter. The funny thing is just now I received another newsletter from ebuy promoting the same Extra Value PC, but with Vista Ultimate as a package. Of course price is increased, £264.98. It is making things worse.
As many friends who know me know I hate Vista, ebuyer does not know what I want. Nevertheless, I can not expect ebuyer CRM system being so intelligent.
可能因为我刚入门 linux 吧，有些方面我还是认为它不太友好。比如在 ssh 状态使用 vim 作文本编辑器应该是绝佳的选择，我不指责它的编辑性能，倒是愣让人看不明白。难道它就非得用晦涩的文字写 manual?
我无奈转向 google，一下子就找到了常人通俗易懂的语言，归纳如下：

今天 Fedora 11 alpha 发布了。Fedora 10 我还没摸熟呢，Fedora 11 就来了，真让我高兴之中疲于奔命。
无意中还发现 drupal, mediawiki, planet, wordpress 都包含在 Fedora 发行包中，这是不是跟 Fedora Project 自身使用了这几种技术有关？我的意思是：为什么不包含别的 packages，比如 magento, joomla, etc?
Fedora 倡导的东西咱就支持一下。不管有用没有，咱全安装了（也就 drupal 暂时派不上用场）。
