I have had Macs since 1995, but I still am not familiar with things such as Arrandale i5 and i7, NVIDIA and the other upgrades people are hoping for on the rumored updates on the MBP's. I am just wondering what these updates will mean for somebody who doesn't do intense things like gaming, music and video editing, etc. I simply browse the web, use Excel, Dreamweaver, Word, Photoshop, a little iTunes, etc. Nothing that my Powerbook G4 can't handle. My screen is cracked and need something new bad, but not sure if waiting to get the updated MBP is worth it to me. How will these possible upgrades affect someone like me? I feel like I should wait, but mot sure why!
