80% of my programing work is solving problems and designing stuff. The only productivity boost I got is when working with proprietary libraries that have most of their documentation in customer support tickets (wouldn't be a problem if I could just read the bloody source code or our company didn't think that paying UNHOLY AMOUNTS OF MONEY for shit makes it better) or when interacting with a new system, where I know exactly what I want, but just don't know the new syntax or names. It's handy, but definitely not a game changer.
