A contrived example, but I'd like to see someone edit a Java project faster in VIM than I do in Eclipse.
Look, I know how to use VIM better than the next guy (you'll just have to trust me on this), but when it comes to writing code for large projects I can't stand using VIM. It makes me feel like I'm looking through this tiny window to my code. Give me a mouse and a powerful IDE, and it's like I suddenly have a 10,000ft view of the world.
