Hi everyone -- I've scheduled my first Genius Bar appointment ever for tomorrow because the ethernet port on my 8-month-old 15" MacBook Pro (the previous generation with removable battery and ExpressCard slot) has stopped working. I have a couple questions: 1. I can't be without a laptop for even a single day. This is my work computer. I need to get in and out of that store within a hour or two, ideally. What is their policy for this type of problem -- how is it usually handled? Might I be able to convince them to simply swap me into a comparable (or newer) MBP right on the spot? 2. If that's a possibility, that brings me to my next question...I upgraded the RAM to 4GB and put a faster and larger hard drive in this machine than what it came from Apple with. I assume they'll transfer these over for me if they give me a new machine? Thanks!
