Show all apps on home screen, or replace home screen directly with app drawer

Is it possible to customize my Android device (in this case, Samsung Galaxy S2) to not have a home screen, but only the app drawer? If I can give example, it would be an iOS; you unlock and you are instantly on applications. The reason for this is I don't really use widgets at all, and I don't see the point in having a home screen only for apps shortcuts if I would have only menu (app drawer).
