My wife and I each have apple products (iPhone, ipad) and windows laptop, desktop. Each one of us has a separate apple id. We are looking for a cloud storage service where we can store our apple content (e.g. iPhone photos), but also other files (e.g. camera photos, movies, documents etc.). The icloud service seems convenient since we are both using apple products. Can we use one icloud account for both of us? If yes, how?
