I have a Macbook Pro that I bought in September of 2007. It is 2.4, 2GB Ram, and 160GB HardDrive. I do use Photoshop, Dreamweaver, Lightroom, iMovie, Garageband, and other intensive programs. many times I max out my Ram and my computer gets sluggish. My computer went in for a repair in which they replaced the display. Other than that my computer is pretty much in perfect condition. My mother's company has offered to get her a new computer for her job. My mom is not tech savvy so she said that I could tell her which computer to get and she would give it to me and I would give her my machine. I am tempted to get the new MBp 2.8, 4GB, 320 GB, but I am concerned that since this is a Rev. A machine, I may get stuck with a problem that I do not have on my current computer. A decision needs to be made by the end of the week... What do you think?
