K so i just bought a unibody macbook and that sucker scratches so easily. I was just cleaning the thing with a cleaning cloth and it scratched it Please Register or Log in to view images there must of been something on it but still wtf!!! I find that pretty ridiculous to scratch so easily but its all good because were it scratched is where i rest the palms of my hands to type. Needless to say im throwing away this cleaning cloth. I was also wondering if its worth buying a external hard drive for the time machine program. It seems pretty worth it but how big should the hard drive be like 100GB? Also it seems that my battery seems to run out fast. I will just be browsing the internet and get maybe like 2-4 hours of battery on wifi and now im at a friends house and im plugged into the internet via ethernet cord and my battery display says i got 5 hours could that make such a big factor? When im on the bttery supply i put the brightness down to 4 lower than max.
