Not /exclusively/ ARM, but having their own silicon is helping more than hurting. Personally, and along the lines I think you're getting at, I think Microsoft is in a weird spot of trying to hold on to legacy compatibility for longer than they should and taking some UI gambles that aren't paying off ("again", if you count Windows Phone). Maybe their own chips would help, but that alone isn't the dealbreaker.
