Hey everyone, I had an original first generation MacBook Pro that just got replaced with a new 15" MBP. On the retired one on the right side where my palm rests I realized that acids from my hands had corroded the case. Does the latest generation have the same affect when exposed to my hands for a long period of time? I purchased a cover for the palm resting area however I do not want to use it as it takes away from the looks of the computer. Thanks.
