And even then, item 2 is a simple example of how attention to seemingly slight details can draw the eye to site features without resorting to a big button.
It also sets ambience and establishes your brand image subconsciously. You wouldn't try serving $50 steaks in a run-down diner, so why would you try to sell an upscale product on a site with no attention to detail?
Not that a big button isn't always out of place. I do think that the elegant details applied to a relatively simple design can help bring the quality of the design up. Simple touches help make a simple design a pleasure to use.
