how is better thought the fact that when you are in finder and then you press enter, you are going to rename a file? because in order to open/execute on a file you must press command+O... You should be careful of "windows bias" (or whatever, I just made up the term). Just because we do something one way in windows, does not mean its better, just what we are accustomed to.
