Preface this by saying I am absolutely no computer techie. So these questions may sound retarded... but here goes: 1) I currently have a powerbook G4 and need to upgrade. My rig supposedly runs @ 1.5 GHz. I was going to get the new 2.66 GHz 15" macbook pro, but I also see that Apple is selling refurb 3.06 GHz Intel Core 2 Duo macbook pros. Does this mean that the Core 2 machine is twice as fast as my current machine? Or does it not work that way? I know the 2.66 GHz machine is Core i7... is it more important to get the most recent processor or the most speed? Does the speed rating really translate to performance, and if so, why is the current fast machine slower that the previous generation? Since I (obviously) rarely upgrade, I just want to make the right decision. I use Photoshop a lot--if that helps give you some insight. 2nd question: when I bought the powerbook there were problems with the keyboard keys touching the screen when closed. Oils from fingers could eventually etch permanently into the screen. So I bought a little leather-like pad to put between when closing the machine. What's the story today? Has the design changed enough to alleviate this? Does anybody use these pads anymore? I'm a photographer, so a pristine screen is really important to me. Thanks, I really appreciate any insight.
