I don't know which if the two models to pick. I currently use a 2009 model and I constantly get the beach ball, so I've decide to swap it for a new one. But I don't know which to choose. Is the more expensive one considerably better? I mainly use it for browsing and watching movies. I don't play games on it. But I need it to run quick, I'm getting tired of loading times ---------- I'm also considering the cheaper one with 8GB RAM versus the more expensive one just as it is, no upgrades. Don't know which is faster of these two..?
