It's interesting to see one of my old threads revived from a while ago
And yes, I have moved on from trying to protect the trackpad - other than a bit of dust, it still looks pretty darn new.
My previous Macbook Pro was approx 1.5 years old and you could see parts where it seemed "worn off" on the trackpad (as well as the spacebar, and a few other keys). I am wondering if the Magic trackpad would turn out the same?
I bought a retina 13inch MBP a few months ago and decided to put a BestSkinEver shield on the whole notebook, including the trackpad. I was worried about altering the feel of the trackpad (it feels so good!) but after 15 minutes I was over it, and it still feels great and works even better. If I ever resell my notebook I know i can get more money since it will look brand new.
