I've just ordered a mac for the first time and I've heard that the macbook pro can get some unpleasant scratches on it. Just wanted to know whether or not the scratch threat is more than the average plastic notebook out there. I'm planning on sticking it in my bag a lot (which has a padded laptop comapratment). Is the htreat big enough for me to have to invest in a hardsheel cover/skin or sleeve? Or will just sticking it into the bag laptop compartment be sufficient? Is there anyone who's managed to avoid any scratches over a prolonged period of time or is it something inevitable?
