在 Arch Linux + KDE 下生活了近两年，虽然不能说达到有深度的 Linux 用户的境界（写个 bash 的判断语句都还得查查手册），但是也受到了很大的影响。关于操作系统论战已久，我不会大喊 Arch Linux 是世界上最好的操作系统。我只是遇到了太多贴心的东西，让它逐渐成为了我的信仰——抱有的信心和信任所在。
更新/软件管理
无论是软件更新还是系统更新，在 Windows 下面都是一件极度痛苦的事情，单独的软件更新要手动下载安装包，然后手动重新安装一次，而且安装程序还有可能有各种迷惑性选项乃至破坏性的行为，以及安装目录的选择（我已经很久没有思考过这个问题了），而系统更新，有的推崇直接关掉吧，用第三方工具完成，也有坚持系统自己的更新功能的，每次更新之后关机开机都会耗费超过平时十倍乃至几十倍的时间，在没电的时候和情况紧急的时候，开机看到长时间的 Windows 正在配置... 又不敢做任何举动的心情真的是让人着急的不行。Arch Linux 这边，更新永远只需要一句 pacman -Syu 了事，不管是所谓的系统更新还是软件更新，所有软件都自动为你下载，为你安装，根本不需要操心安装目录这种傻到家的问题，如果遇到急事，随时都能 ^C 停下这个过程，下次执行更新的时候接着干活，开机关机也不会有什么特别的变化，一如既往地让人没时间冲好一碗麦片。
应用程序
还在用 Windows 的时候我渐渐感到对桌面的不满，为什么会有这么多图标，还有人把它当垃圾桶，让原来壁纸失去光彩，还给人了无限手残的可能。尝试了 ObjectDock，开始菜单， winkey + R。最后到了 KDE 遇到了 krunner ，让我终于能够尽情欣赏壁纸的同时超快地启动我想要使用的程序。
窗口管理器，在 Windows 的时候，我曾经感叹这个应用程序的半透明真是神来之笔，那个程序的置顶功能真是方便，要是 xxx 也能这样就方便多了。到了 KWin ，我可以尽情让合适的程序半透明、置顶/底、全屏、无边框等等，甚至还能给窗口制定规则来限制他们的表现。全局快捷键、虚拟桌面、键盘布局调整等等，这些原本想都不敢想的东西，现在已然是我的好伙伴，这在 Windows 几乎是不可能的事情。
