It makes sense, I guess. As programmers, we naturally spend a lot of time with our editors of choice, so we become very attached to them, both emotionally and practically - with Emacs, at least, you accumulate your customizations and extensions over time, and you want all the time and effort you put into learning and customizing to pay off. And with any editor, there's the muscle memory - it's like you're offloading certain tasks to a dedicated piece of hardware, thus freeing your mind to focus on the task at hand. It's a kind of "lock-in", if you will, but it's the kind that enhances your productivity.
