See my comment above. I spend a lot of time typing, even though I reuse a lot of code. (I write a lot of code: http://github.com/jrockway)
It's nice to think that code types itself, but it doesn't. If you have no ideas, then it doesn't matter how fast you can express them as code. If you have a lot of ideas, though, you don't want to wait for your fingers to slowly tell them to the computer. You want the computer to know quickly, so you can move on to the next task. That's why typing is important. There is no brain/computer interface yet, so you have to do it with your hands and the keyboard. Suboptimal, but them's the breaks.
