The new facebook will not allow a user to show all their information or applications on one page.  Instead of just going to one webpage a user has to click on many different tabs to see their friend's information. Also, if you want to check your wall for new wall posts it is more difficult since the user will have to scroll through all the activities that they have done on the new facebook along with all of your friend's wall posts that they have left for you to read.  The old facebook did not show everything that you did on facebook on your wall, so it was easy to check your wall for new messages.
