Oh me too, I love when a tool solves problems I didn't even know I had, until I have them, I look for a solution, and poof Vim (or whatever) has already solved it in a coherent way. If every tool were like that that would be one kind of world, but we live in one that's more interesting. There's some Mark Twain quite like "the world owes you nothing; it was here first", or maybe the Buddha saying "it's harder to soften the earth than it is to wear sandals". I like to think that sandal-making is a core engineering skill, whether you're a carpenter or a computer engineer.
