I'm all for Apple making some changes. That being said, these aren't the types of changes that will move things forward, at least not in my opinion. As others have said, this has the look of other devices which haven't performed that well. The design is simpler, but that doesn't mean it's better. In fact, I'd say it matches how other companies have tried to revert to cleaner, simpler, older styles and designs.
The map app in particular is pretty bad. Of course, the old logo for their map app shows a route sending a person off a bridge, but the new one is seriously dated. Younger users might not even understand what the map logo stands for. This isn't the direction you want to go when your base consumer is upset that the company has drifted more and more toward their parents.
