Underexpose or not is one's choice. And I think they don't think smartphone should be the only way to take landscapes so neither do we should claim a certain format should be the only way.To me it is eye opening that with the iPhone 4 I owned, someone can take a good landscape.
Anyone can download it?Apparently their server is not good enough.
