Hi, quick question. I currently have a old 13" Early 2009 Macbook with 2 GHz Intel Core 2 Duo and 2 GB of ram. It has Mountain Lion installed and its quite slow really and locks up quite a lot. Im thinking of upgrading to a Macbook Pro (used one as only want to spend around £600). Im wanting to know if I will see much difference? The other option is to increase the ram to 4gb and add a bigger HD. Also have a iPad 2 and iPhone 4s but im thinking of selling the iPad if I upgrade to a Macbook pro as to be honest, I dont use it much. Thanks!
