Hello there. I just bought my first mac about two months ago, it's the middle model macbook, and I got it right after there was that little improvement in memory and hard drive space, which is great. I've been really happy with it so far, but I'm a little worried whether I'm handling it properly or not. I've been noticing some scratches on the glossy screen, they're very small and superficial and I don't even see them when I am using the computer, but I was wondering if it's not a good idea to put this (http://www.greenhome.com/products/housekeeping/all_purpose_cleaners/114085) microfiber polishing cloth between the screen and the keyboard. I have to take at least 2 hours worth of transit rides from my home to school each day, and so the macbook goes through a lot of traveling. I've been trying to take precautions by placing that polishing microfiber cloth between the screen and the keyboard, and placing it in the padded laptop compartment of my backpack, and always putting down my backpack in such a way that it's my macbook's weight on my textbooks and not the other way around. So is what I've been doing so far alright, or is the microfiber cloth a culprit in this? It's not a big deal now, but I'm just worried that it would get worse in the future. How do you folks take care of your macbooks regarding frequent travel and all that? Any tips/advice to share? Thanks!
