I've found vim is the finest code editor I've ever used, but it's a crap IDE in terms of organizing a project, compiling, and debugging all from one software. Disclaimer A: I haven't spent a ton of time trying to make it an IDE, and B: I have the misfortune ;) of being an iPhone dev, and only Xcode plays nice with the devices and simulator.
If anyone can prove me wrong, please, please, please do so, because vim is just awesome for editing code.
Not entirely true. Appcode, an alternative IDE, also works fine with development on devices and the simulator. I haven't heard of an open source plugin to do this yet, though. So no way to do that for vim. (There's a vim plugin for app code though, it's not perfect but ok).
