Hello. I've decided to purchase a 15" MacBook Pro, but need some feedback/advice on the processor choices. I don't work with graphics or video or audio. I mainly work with databases and text files. However, I have have VMWare Fusion running all of the time to access GoToMyPc and to use my PC-based accounting system. An Apple representative said I should do fine with the 5400 rpm hard-drive and it would save on battery life, which is important to me. However, I don't know much about processor speeds and their affects on battery life and speed and how it relates to my situation of always running the VMWare Fusion/XP operating system. Should I go with the 2.66, 2.8, or 3.06? Thanks in advance for your advice!
