Touch typing for coding felt awkward because there's a lot of special symbols that are kind of hard and unintuitive to make if you try to touch same keys all the time. Also I wiggle in my chair quite a bit and believe it's essential for healthy sitting. I feel like touch typing could interfere with my wiggling.
My style of typing is yet another factor why I get infuriated when I sit in front of a Macbook. For some reason Mac keyboard is about 3/4 of the key to the side of where I expect it to be (and literally every other keyboard is exactly where I expect).
