What about the cost of not learning it? Like potential neck pain, slower thinking, over-reliance on code completion (it takes your brain some processing time to decide what will be long enough to produce the right completion but not too long to waste keystrokes), less ability to communicate effectively.
And the cost of learning it is laughable. You just have to practice a bit for 3 days to learn to get the right fingers on the right keys from memory. The key to learning quickly is that you try to reproduce some text on the screen while NOT LOOKING at the keyboard, and you go as slowly as you need to avoid looking up (well, down), it doesn't matter if it takes 15 seconds for one keystroke at first. The important thing is to try a recall from memory at all costs before you finally know you've really completely forgotten and then look it up. And you do like this for each letter. You'll reduce your latency and learn the whole layout quite fast. After that it's just a matter of practicing for a few weeks and you'll be up at a reasonable 30wpm in no time.
