This completely ignores those of us who fill forms by tabbing through fields to stay on our keyboard. TAB into the country field, type 'Uni', down-arrow a couple times to United States. TAB to the next field. Simple. Having the suggested country at the top for mouse-bound folks helps, but a standard select dropdown can also pre-select a default choice (via the 'selected' attribute).
