The only upgrade 4Gig ram I'm thinking I have had this MacBook for a little over 3 years. It's time to buy a new one or upgrade. Before this laptop I bought a power Mac 7200 80/av and I actually still use it. I don't really want to get outdated again so, should I just upgrade my ram to 6gig ram upgrade the hard drive and upgrade the OS to the latest or buy a new MacBook? I just need some opinions the good the bad.
