I tried out an iPad app called Koder, it was nice but still lacked some things.

Your post has got me wondering about Vim again.. :) Making the switch to Sublime Text has got me appreciating a more shell-like interface for some things.

Have you ever found yourself wanting to code and not have an internet connection? I think that's a pretty rare scenario, I'm rarely offline.

I haven't wanted to code offline for months. Maybe if I flew for more than two hours I'd miss it. Even the trains have wifi in Germany.

The few times I have wanted to code offline, I've also wanted to look something up >.<

Haha, that's really true. I rarely code offline, maybe it's just another umbilical cord that we should be examining.

Between having tethering and generally ubiquitous tethering, we should be good.

I think I want to try getting into VIM again. Is there a good resource site you like, where I can find a decent guide and some pointers on where to find some language dictionaries? Totally off topic but I'd appreciate it.

I recommend just running "vimtutor" in terminal once you've installed Vim. It's the best introduction. Far better than the online tutorials that sometimes pop up on HN.

Once I got the basics down (15 minutes in vimtutor), I noticed enough productivity gains to use it immediately for note taking and scripting. Then I just decided to jump in and use it for a real project. I learn new hotkeys, plugins, and config tricks every week and I just feel my productivity inch its way up and up.
