I'd say vim is definitely worth learning. I picked it up last summer, and it is now my editor of choice for just about everything (java is a stretch, but doable when I don't need extensive analysis support). As everyone has already affirmed, it is a wonderfully efficient tool. For what it's worth, I only learned a fairly small subset of vim's features (which took a day or two) from a graphical tutorial, and a few odds and ends from here (long read), and the search and replace functionality, and I was hooked. I've learned things since then, but at my leisure. I'd say the learning curve flattens out at this point, but then, I was using it pretty heavily and was surrounded by others who were, too.

vi/vim的两个优点:

它很轻 它几乎安装在每个*NIX系统上

是的，一定要花时间学习至少一点'vi'和'vim'。它旅行很好。

当你面对一个你没有安装能力的Unix/Linux/Mac系统时，你永远不会被困住。即使在Windows上(如果你有安装功能)“Vim”是免费且易于安装的。(而不是把你的学习曲线完全投入到像UltraEdit这样的东西上，尽管一个优秀的编辑器可能并不总是适合你……)

学习vi可以帮助你学习其他工具，比如sed和regex:一般来说是可迁移的东西。

另外，如果你想成为一个真正的极客，你只需要知道'vi/m'，否则你看起来就像一个骗子;-)

我学过Vim。这并不费劲。现在我绝对喜欢ci”ci(cw V:s/from/to/g

I too put off learning vi or vim for many years. Matter of fact, I use to make fun of the "vi guys" who always seemed to be doing finger aerobics. Then, as I moved away from Windows and over to Linux as my primary OS, I had to become more familiar with vim. It was a learning curve and it still is. After 9 years of using vim on a daily basis I still find myself learning new and faster ways of doing things. What I use to think of as "finger aerobics" actually turned out to be an extremely efficient way of being productive. I can now do a whole lot more code development in a whole lot less time and effort than I ever did prior to vim. And as I'm sure you know vim runs on about every platform out there so you always have it when you need it. Also, if you like GUI's they have GUI versions for most platforms. Personally, just like the mouse, I don't want to see a menu bar, scroll bars, etc. cluttering up my editing window(s).

如果你决定尝试一下vim，我强烈推荐O'Reilly的《vi Editor Pocket Reference》一书。它很便宜，如果你只是学习vi (vim)，它是很棒的。完整的vim书籍也很好，但口袋参考给你所有的基础知识，快速高效。

恕我直言，学习新东西总是值得努力的。我建议你打印一张小抄单，强迫自己日复一日地使用它。
