Yes, it's detrimental because it's distracting. It interrupts my concentration when I make typing mistakes, or can't get the code written down fast enough. I want to write it down fast, because I can only hold so much in my head, and the faster I can write down an idea, the faster I can move on to the next one. Once everything is down, it's much easier for me to look at the whole, and edit it (refactor, etc.).
