I'll second the Shortcat recommendation. Got a license pretty much as soon as I installed and used it (after the trial period, because I can be stingy). Between it and Alfred, I can do most everything I need from the keyboard.
For me, the most obvious/immediate "bang for the buck" is enabling bluetooth when I sit at my desk. If I don't, and use my Macbook from the living room, the distance is just awkward enough, on bad RF interference days, to continuously get the "Connection lost" and "Reconnected" message for the mouse.
