So much this. Writing English sentences on a typewriter with touch typing works well. But many people don't write prose exclusively and computer keyboards are not typewriters so it's no surprise that touch typing doesn't often work so well.

As a programmer I find typing {, } and \ with the pinky the biggest problem. There are layouts especially for programmers. The ones that I'm aware of are Programmer Dvorak[1] and Neo[2].
