Hey guys. Well my warranty from best buy is going to be used any day now. My macbook had three repairs done within last two years and well my DVD drive is messed up. It doesen't work at times and just makes the whole laptop vibrate and shake. So as far as i see it i will be gone in a month or so. So here is the question, has any of you went from mac book to mac book pro 15". I use my laptop everywhere and i am usually on the go from school to home to library and so on. But i drive and I train in MMA so the weight is not an issue. I'm just wondering if there are any downfalls you guys experienced with going for bigger size? I do about three things at once on my mac so i think more screen space is most excellent! I have been getting sick of little room on my macbook for the last few months. What are your opinions? PS: The second GPU is nice to have, but gaming isn't on my list for the new laptop at all. I have 360 for that!
