>>If you can point to a single project that was done on time and without bugs because it was edited on vi/vim then you have a point.

Software projects are late on schedule for reasons nothing to do with typing speed. Learning text editing is only important for you to make comfortable while you are doing other important tasks.

In other worlds like Java, Intellisense and auto-complete rule the world. You can't do any work sanely without those two things. In fact not knowing them might cause a delay in delivering projects. Using them only brings you on plane with other Java developers. Its a need not an advantage.
