I don't have a strong opinion, but also think that mine would be irrelevant anyways -- isn't what matters most here the research they have undoubtedly done to understand how the UI affects their various customers and their needs? The certainty people often have as to UI design is amusing in light of how successful this line of products has been, as if their small and selfish opinion (or mine!) could somehow be more correct than the millions these guys have invested in getting this right. And not to the problem they or I _personally_ have, but to the problem of shipping a product used by probably billions of people across hundreds of cultures. I have no doubt that if you (or I!) were in charge of design, guided only by our personal opinions, the product would have completely failed.
