It's a sizable issue for me. I write every piece of code several times: once to get a sense of the problem space, once to prepare it for review, once to incorporate feedback review and once to adapt it once a new customer has as similar need, an tweaking my code for a couple hours saves him a couple of days. The technical ability to type fast is critical, thus having good tools is critical. Several areas: typing comfort, code search, autocomplete, code refactoring, plus high signal / noise language.
