10-3-1 is an interesting technique, if you can afford it. It seems like a much better approach than iterating on a single design because iterating means you are slowly evolving from one design to the next. But having 10 different designs to cull from would provide a much broader range. I think the key, though, is owning the entire system, hardware and software. They can integrate everything with their eye for detail and no other vendor can sully it with corner-cutting.
