Beta by definition is functionally complete and needing further testing to iron things out. You are sadly misguided if you think Apple would reveal something and then let millions of people have it with major changes in mind within months. Why embarrass themselves by having people test and USE the solution day to day otherwise?
Current casual users will suffer most from this. They are not going to be smitten even with the expected cute Maps commercials that I am sure are coming. Not because it is different, but because data is missing and the level of details sucks compared to what even iPhone 1 had. It's ugly too but that is subjective.
