@muawyah5-It is too old indeed, but old models were so different from all new model specially retina models. Newer models don't have ethernet port, light sensor when sleep and many more. Some features in new model were remove due to apple's aim of thinner mac. So every model, either old or new are special in different ways. It is all about end-users preference, beside this macbook is complete working 100% regardless of its model. Thanks
